MINUTES
1. Chairman's Remarks
1.1. Welcome. Prof. Stepto opened the meeting by welcoming the attendees
and thanking them for their hard work during the past year. He considered
it to have been a very active period.
- The Minutes from the Geneva
Meeting were approved
without changes.
1.3 Matters arising
from the Geneva Meeting.
All the matters arising and covered in the present Minutes.
1.4. Publications
since Geneva
1.4.1. Definitions of terms
belonging to the Non-Ultimate Mechanical Properties of Polymers (Recommendations,
1997) Pure Appl. Chem. 70, 701-754 (1998)
1.4.2. Source-Based Nomenclature
for Non-Linear Macromolecules and Macromolecular Assemblies (Recommendations
1995) Pure Appl. Chem., 69, 2511-2521 (1997).
1.4.3. Chapter 6 in Principles
of Chemical Nomenclature, Blackwell Science Ltd., Oxford, UK,
1998, refers to polymer nomenclature. Dr. Metanomski participated
in this book, that has received already very favorable comments.
1.5.1. SDIC Recommendations
In view of the extended
discussions during MACRO98, regarding recent Strategic Development
and Implementation Committee (SDIC) recommendations, the matter was
not pursued further. Following the Chairman's invitation, there was
no wish to reopen the matter, especially since there will be a complete
description in the Division Meeting Minutes. The subject was deferred
until the Berlin General Assembly in 1999.
1.5.2. Minutes received
from Dr. Barry Whyte
They refer to the joint
meeting held by IUPAP-IUBMB. Dr. Kahovec and the Secretary were instructed
to review them and see if they contain anything relevant to the Purple
Book. (KAHOVEC and BARÓN).
1.5.3. The Staudinger
Letter - Polymer and Macromolecule
Prof. Stepto reviewed the
matter recalling that Dr. phil. Magda Staudinger Woigt had died on
April 21, 1997. She had published a note in the journal TERMINOLOGY
[3(2), 343-7 (1996)], regarding her husband's work and
the case of the terms "polymer" and "macromolecule".
Prof. Jenkins and Dr. Metanomski had written a letter in response,
before her death, that was published in the same journal after her
death. The Secretary was instructed to incorporate a brief abstract
of all these documents into the Minutes of this Meeting (as follows):
The gist of the matter
revolves around the usage of the words polymer and macromolecule.
In her letter to TERMINOLOGY, Frau Dr. Staudinger-Woigt, on the basis
of her late husband's (Prof. Dr. Hermann Staudinger's) opinion, considers
that the word macromolecule should be used exclusively, disregarding
the term polymer as "obsolete"(sic). All this supported
by the fact that the latter word, due to its original formation from
the combination of two Greek words, can be applied to any structure
composed by parts without any special indication of the nature of
the linkage between them. On the other hand, the word macromolecule
precludes the existence of chemical bonds among constitutional units
that are themselves molecules of various sizes
Frau Dr. Staudinger-Woigt
further indicated in her note that she had received opinions in favour
of using macromolecule in addition to polymer. In further
response to her request for arguments pro and contra, Prof. A. D.
Jenkins with the cooperation of Dr. V. M. Metanomski, sent a Letter
to the Editor of TERMINOLOGY pointing out very clearly the recommendations
regarding these two terms that resulted from the work of IUPAC Commission
IV.1. Consequently, both terms have now separate definitions that
identify them unequivocally, therefore macromolecule refers
essentially to a molecule while polymer refers to a substance
(cf. Glossary of Basic Terms in Polymer Science, Recommendations 1995)
Pure Appl. Chem. 68, 2287-2323 (1996).
1.6. Timetable for
the Sydney Meeting
The
new format for the Agenda (see Annex A),
that had been circulated to all attending Members prior to the Meeting,
was accepted after a short discussion.
No formal decision was
considered to be necessary since this meeting proceeded essentially
along the proposed lines with the sole exception that instead of devoting
continued time for the WP individual sessions they were interspersed
with sessions of the full Commission (Annex D).
In the future, Coordinators
will inform the Secretary on meeting time needed for their WPs when
they receive the tentative Agenda, so that a list can be prepared
by the Secretary to facilitate organization of the timetable during
the first hours of the meeting.
2. Projects to have been Submitted for Public Review
2.1 18/87 Liquid
Crystals
Profs. Stepto and Barón
reported on the present situation. The document is now complete after
the comments and suggestions of members of the International Liquid
Crystal Society (ILCS) have been incorporated. Minor editorial corrections
are now being introduced and the final draft will be sent for public
review in early September.
Prof. Shibaev expressed
his satisfaction at the completion of the work, considering all the
efforts devoted to it by so many colleagues. He wished to thank not
only the members of the WP but also to all others that cooperated
in its preparation. He further suggested that the document be published
not only in PAC but also in liquid crystal journals and offered to
contact the editors for this purpose. Prof. Stepto replied that, although
this is very desirable, it can be done only after publication in PAC.
By May 1999 comments from
public review should have been received and the necessary changes
made so that the final document can be published before the Berlin
Meeting or, at least, ratified during it.
The draft for public review
will also be sent to the members of the WP and to all those that were
active in its preparation. Profs. Barón and Shibaev will update
the list.
Actions
- Send the Draft to Prof. Stepto
for editorial checking by 10 September 1998. (BARÓN).
- Send for public review by 15 October
1998. (BARÓN).
- Check list of experts and send
the Draft to them and to the WP by 31 October 1998. (BARÓN
and SHIBAEV).
- Post the document on the Commission's
web site (WORK).
2.2 19/89 Revision of Regular Single-Strand Nomenclature
Dr. Kahovec reported on
the work done by the WP, indicating that only small amendments in
words and nouns were necessary. The draft was sent to the Commission
Membership and to outside experts. Only five of the former and three
of the latter responded (Dr. Hans-Georg Elias, Prof. T. Tsuruta and
Prof. J. G. Traynham, Secretary of the Organic Chemistry Comm. on
Nomenclature).
One general comment was
the need to update the organic names. Dr. Kahovec feels that he can
cope with the necessary changes and prepare the final draft for public
review.
Prof. Stepto indicated
that it had been agreed with Dr. Work that all documents that go to
public review will be placed on the Commission's web page. The matter
was referred to Dr. Work the following day, when he participated in
the meeting.
Finally, the four recommendations
made by the Commission during the Geneva Meeting were reviewed.
- The word "polymers" in
the title was changed to "macromolecules".
- "Degree of unsaturation"
and "state of hydrogenation" are not used interchangeably
throughout the document.
- The final draft, now adequately
structured, will be completed.
- The draft will not contain Dr.
Fox's recommendations regarding cyclic structures because they
are the subject of another project.
Actions
- Make necessary revisions to the
document, write a summary, prepare a list of experts consulted,
and send to Prof. Stepto by 31 January 1999 requesting public
review (KAHOVEC)
- Prepare a letter of approval and
send to Prof. Baron by 15 February 1999 (STEPTO).
- Request letter of approval from
the Division President by 28 February 1999 (BARÓN).
- Send the approved document to the
Commission, the experts consulted, the IDCNS, and the Secretariat
to request public review by 31 March 1999 (BARÓN).
- Post the document on the Commission's
web site (WORK).
3. Projects in Preparation
by Working Parties
3.1. 21/93 - Generic
Nomenclature
Prof. Maréchal reported
that the WP agreed to introduce some changes to the draft. Most important
was the subject matter starting on page 3. It was agreed that it did
not belong to this project and will become a feasibility study (see
F-19).
In this document the following
changes will be made:
- Pages 3,4 and 5 will be eliminated.
- Rule 1 will reference the Purple
Book and be included in the Introduction.
- In Rule 3 names will be written
as:
polyG: A
because it is less confusing.
- On page 7, in examples 3.4 and
3.5: All references to bisphenol A will be replaced by quinone
and carbonic chloride by phosgene so that it reads:
[(phosgene-alt-hydroquinone)]
New wordings were proposed
for pages 10 and 11. All separations are to be eliminated so that
names are written:
poly G,G',G''
because, although the use
of hyphens would correspond, it is common English practice to drop
them when not really needed. One continuous word is therefore acceptable.
Titles on page 9 are to
be eliminated because they are unnecessary as well as the last line
on page 11. Also the addition of a note after Rule 5 was recommended.
Since class names are not
unique, this ought to be so indicated. Consequently structure I has
two possible names:
The long name was questioned
and the matter was settled by vote, with 8 (eight) in favor of the
long one, 6 (six) against it and 1 (one) abstention. The words will
be included in English alphabetical order.
Dr. Kahovec found a pleonasm
in Rule 3, that was changed accordingly. The second sentence in Note
6 was deleted because it is unnecessary, as well as the title on page
13.
Prof. Maréchal objected
to the manner in which crosslinking is indicated on page 15. To this
effect -styrene does not make clear if it refers to a monomer, an
oligomer or a polymer. The final version should be checked.
The use of amic acid was
discussed extensively. Since it is of common usage in industry and
also is consistent with Chem. Abs. nomenclature it was finally accepted
in the expression:
For structure II, polyetherimide
was accepted and the line between I and II was deleted.
In Example 5.3 the word
quinoxaline was replaced by phenazine.
Prof. Stepto questioned
the Appendix and suggested a new wording.
The changes approved were :
-removal of pages 17 to
19 because they contain normal organic nomenclature and are therefore
unnecessary
-language corrections sent
in by Prof. Jenkins for pages 2 and 5
-the word polymers will
be replaced by polymer molecules throughout the text.
Actions
-
All corrections are
to be made (MARÉCHAL)
-
The amended Draft
should be sent to the WP and at least twenty outside experts by
31 August 1998 (MARÉCHAL).
-
Comments back to
Prof. Maréchal including suggestions of experts (both industrial
and academic) by 30 November 1998 (WP).
-
Send list of experts
to the Commission Secretary (MARÉCHAL).
-
Expert comments are
expected back before the Berlin Meeting and should be circulated
to the WP (MARÉCHAL).
-
The document is now
considered complete and ready for public review after the Berlin
meeting.
3.2. 22/93 - Guide
to Polymer Terminology
Dr. Metanomski indicated
that he could only provide a progress report and that there is still
a long way to go with this document. Some chapters, although advanced,
are not ready for inspection. Other chapters should await the publication
of the corresponding documents, so that the information they contain
could be used. However, he emphasised on the need to establish limits
as to what should be included and how comprehensive the material should
be.
Prof. Barón asked
when the Guide is expected to be published. Dr. Metanomski said that
it would take not less than two years. At this point chapters were
reviewed individually and it was concluded that only chapters 2 (Polymerization
Reactions) and 8 (Nomenclature) might not have the corresponding documents
ready in time. As a result, a cut-off period of two years was considered
to be convenient and although Dr. Metanomski retires form the Commission
in one year, he wished to continue in the project. In any case he
stated that a final editorial unification review will be absolutely
necessary.
The state of the chapters
at present is as follows:
Chapter 1 - Basic Terms: A draft exists
Chapter 2 - Polymerization
Reactions: Awaits the document
on polymerization reactions (26/95). Possibly the document could go
to outside experts and for public review by the Berlin meeting, so
that publication could not be expected before 2002. Therefore, this
chapter could be completed by 2001.
Chapter 3 - Macromolecules
in Solution: A new draft is
to be prepared following Prof. Kratochvìl's version (STEPTO).
Chapter 4 - Crystalline
Polymers: Has to be finalised (JIN).
Chapter 5: The present draft has to be made consistent with the
Liquid Crystals document (BARÓN)
Chapter 6 - Degradation
and Aging of Polymers: Is
complete.
Chapter 7 - Mechanical
Properties of Polymers: The
chapter is now available and comments can be made (WORK).
Chapter 8 - Structure-Based
Nomenclature: Dr. Metanomski
proposed that the following list of topics should be included:
Other possibilities to
be considered are:
The following points were
agreed:
The size of each chapter
should not necessarily be in proportion with the document or documents
from which it derives. The reference numbering for definitions should
be in the form: ([ reference number], Definition number). e.g.
([1], Definition 1.1) Put to vote these points were approved
unanimously.
Dr. Metanomski also indicated
the need for a list of terms as an Appendix and an index, in a different
font, for the terms actually defined.
Members of the WP were
urged to ensure consistency between the chapters and the documents
from which they derive.
ACTIONS
-
Contact directly the Chapter coordinators and
request that all chapters become equally advanced as soon as possible
(METANOMSKI).
-
All coordinators should send copies of their chapters
to Dr. Metanomski and their WPs before 31 December 1998 (CHAPTER
COORDINATORS).
3.3. 24/93 Multi-Phase
Polymeric Materials
Dr. Work made a general
description of the present state of the project and listed Prof. Papisov's
comments. Consequently his suggested changes were discussed and incorporated.
Note was rewritten starting
as: Although the...
No limits were established
for the word nano, because it is understood that it refers
to 10-9.
1.28 was rewritten as:
A bonding in which the
surfaces of the two different substances in contact with one another
are held together by intermolecular interactions.
Note.
The interactions can
be covalent, ionic, hydrogen bonds or van der Waals forces.
The document was then discussed
by the Commission and further corrections were incorporated. It was
agreed that all terms should be alphabetized and an index be provided.
The term, miscibility
gap was not considered to be clear and the WP was instructed to
solve the problem. Chapter 5 was removed and the Introduction will
have to be amended accordingly.
ACTIONS
- All corrections to be incorporated
(WORK).
- Solve the definition of miscibility
gap. Don Paul will be contacted and, if necessary, eventually
two definitions could be incorporated (WORK).
- Send amended draft to the WP by
31 December 1998 (WORK).
- WP comments to Dr. Work by 28 February
1999 (WP).
- Names of external experts to be
sent to Dr. WORK. (All commission).
- Send to outside experts(WORK).
- A new version should be ready for
the Berlin meeting (WORK).
3.4. 25/95 Asymmetric
Polymerization
Prof. Hatada reviewed the
work carried out and raised two points that he considered still needed
agreement.
1. The definition of "asymmetric
polymerizations". Finally accepted was:
A POLYMERIZATION WHICH
PROCEEDS IN AN UNSYMMETRICAL MANNER IN TERMS OF CHIRALITY UNDER THE
INFLUENCE OF CHIRAL FEATURES PRESENT IN ANY COMPONENT OF THE REACTION
SYSTEM.
Although it was considered
to be somewhat vague it is complete and allows to include all possibilities,
especially racemic polymerization. The matter had been discussed with
Prof. Sigwalt who (reluctantly) agreed to this wording.
2. It was resolved to replace
the term "balanced" by "racemic" because of general
consistency.
Prof. Penczek discussed
the use of the words "chirality" and "chiral features"
and it was accepted that they are essentially synonymous.
Finally, Prof. Stepto expressed
the need to change the structure of the document regarding numbering
of definitions and notes. This led to a detailed review with changes
in wording, numbering of definitions, notes and examples. Prof. Hatada
will make them all consistent and use centre of chirality throughout
the document, as a compromise due to the differences found in the
87 and 97 versions of the Gold Book. The WP will discuss and undertake
further changes.
ACTIONS
- Dr. Wilks was added to the WP.
Prof. Maréchal requested that his name be removed from
it.
- The revised document should be
circulated to the WP by 15 August 1998 (HATADA).
- Comments should be sent back to
Hatada by 1 November, together with suggestions of names of experts.
(All Commission).
- Send to outside experts by 31 December
1998 with replies by 1 May 1999 (HATADA).
- Prepare a new version for the WP
by 15 June 1999 and present for discussion in Berlin (HATADA).
3.5. 26/95 Kinetics
and Thermodynamics of Polymerization
Prof. Penczek reported
that the latest comments received had been introduced. He proposed
that all members of the WP send in their comments after checking the
changes.
Linguistic problems were
then discussed in the light of comments by Prof. Jenkins and Dr. Wilks.
Prof. Stepto questioned
Definition 1. A note will be included with the Definition on activated
monomer.
Prof. Gilbert, present
at the session, asked if our definitions are consistent with those
in the Gold Book. Prof. Penczek replied that some terms were taken
from the Gold Book because the need for them was recognized. Furthermore,
some of the definitions in the Gold book cannot be used because in
general they were prepared having a different reader in mind. Therefore,
since we have particular needs regarding definitions we have to cater
for them. There followed a lengthy discussion on referencing Gold
book definitions with different possibilities examined and many alternatives
suggested. As a result
the use of English words in full (e.g. revised, modified, extracted)
was encouraged.
Prof. Horie offered comments
from himself and of Prof. Tsuruta on the term initiator,
suggesting the addition of a second note clarifying its definition
as being consumed or being a catalyst. The remaining members of the
WP had accepted the changes.
Dr. Jones discussed the
last sentence in the Note of Definition 9 and recommended mention
of the cage-effect. The WP agreed to take note of this. He also requested
that methatesis be included and Dr. Vohlidal agreed
to work on this.
In Definition 4 the words
apparent rate constant need clarification and the WP
will continue discussing this particular point by e-mail. Furthermore,
the WP wishes to have possible further definitions sent to them.
The following new title
was suggested:
DEFINITIONS OF TERMS FOR
THE KINETICS AND THERMODYNAMICS OF POLYMERIZATIONS
Also the words Kinetics
and Thermodynamic Polymerization on the first page are to
be replaced by an Introduction.
ACTIONS
- Add terms on methatesis by 15 September
1998 (VOHLIDAL).
- Revised terms and English corrections
ready by 1 October 1998 (WILKS).
- Revised version ready and sent
to WP for comments by 15 October 1998 (PENCZEK).
- Comments back to Dr. Penczek, plus
suggested names of experts by 1 January 1999 (WP).
- Revised draft to outside experts
by 1 February 1999, with comments back by 1 May 1999 (PENCZEK).
- New version for discussion by the
Commission in the Berlin meeting by 1 July 1999 (PENCZEK).
3.6. 27/95 - Polymer
Inorganic Composites
Prof. Jones described the
work done both by the WP (especially Prof. Hess) and external collaborators,
including the preliminary list of terms with some tentative definitions.
Much support for the project had been received but it was considered
that bad habits will be difficult to eradicate and that physical chemists
will, very likely, want too many alterations. The list submitted contained
terms difficult to understand, although many could be deleted as unnecessary
for polymers they may be required by Commission II.3 and vice-versa.
Prof. Hess considered that
this project and Feasibility Study F-13 could be amalgamated. The
suggestion met general approval. Profs. Jones and Hess agreed on a
common title that, after a prolonged discussion, was accepted, namely:
GLOSSARY OF TERMS FOR POLYMER
GELS, NETWORKS, PRE-CERAMIC MATERIALS, AND SOL-GEL PROCESSING.
It was felt that because
the document will contain a mixture of basic and applied terms it
will be useful. In addition, according to Prof. Hess, the inclusion
of processing makes it important for materials.
It was proposed that a
meeting be organized before the end of the year between members of
both Commissions II.3 and IV.1 (Dr. Holland and others, and Drs. Jones
and Hess) to try to reach an agreement on a joint document. Prof.
Horie supported this idea because he considered the combination of
both fields to be very valuable.
It was agreed that Prof.
Mita should join the WP. Prof. Mita said that the document should
be self-contained with extensive cross-referencing, because inorganic
chemists are not too keen on polymeric terms.
A unanimous vote (16 votes)
supported joining the two projects, if, as a result of the mentioned
meeting with II.3, a final decision is reached regarding the separation
or not of the two projects.
Prof. Stepto suggested
checking the Glossary (1996), the Non-linear (1997), the Aging documents
and the Gold Book (2nd. ed.). Prof. Mita and Dr. Kahovec requested
the elimination of organic chemistry terms. Dictionary covered terms
also needed to be deleted.
ACTIONS
- Consult with Commission II.3 about
a joint project (JONES). In case of failure, 27/93 and
F-13 will be again separated and F-13 becomes a project by itself
because it has enough letters of support.
- A joint meeting will be held between
Profs. Jones, Hess, Holland and Dr. Meisl before 31 December 98.
- A final decision about combination
or division of the project will be made during the Berlin meeting.
- If combination is agreed upon,
Prof. Stepto will seek possible funding.
- Commission Members will suggest
additions or deletions to the list of terms and notify Prof. Jones
by 30 November 98 (Al Commission).
- A new list will be circulated to
the WP by the end of June (JONES).
- The list will be discussed during
the Berlin meeting.
3.7. 28/97 Terminology
and Nomenclature of Hyperbranched Macromolecules and Dendrimer Molecules.
Dr. Kahovec reported that
the major problem in this document stems from the need to use organic
chemistry nomenclature and a variety of possibilities were analyzed.
For a solution he proposed a nomenclature based on Regular single
strand organic nomenclature. In this way there is a core unit
or hyperatom that is not repeated, repeating units and end units.
The advantages of this
procedure are that they use current structure-based nomenclature,
establish differences between dendrimers and hyperbranched polymers.
It includes dicentric dendrimers and end units that may be equal or
different.
ACTIONS
- A second draft to be prepared for
the WP by 31 December 98. (KAHOVEC and WILKS).
- Comments from WP by 1 April 99
(WORKING PARTY).
- A new draft is to be prepared to
be submitted to the Commission for the 1999 Berlin Meeting (KAHOVEC
and WILKS).
3.8. 29/97 Cyclic
Macromolecule Nomenclature
Prof. Maréchal reported
that the WP found it reasonable to separate threaded macrocyclics
from the document and possibly start a new project, especially regarding
rotaxanes. This was accepted on the basis of the opinions of Prof.
Maréchal and Dr. Wilks and the name of the present document
is changed to NOMENCLATURE OF CYCLIC MACROMOLECULES.
This decision implied dropping
pages 12 to 16 and inserting a statement that threaded macrocyclics
will be the subject of a separate document. It was further suggested
that a symbol, to be decided at a later date, should be used to identify
a junction. In the meantime, the present description will be tested.
Names on page 9 are to
be restructured. Two bridges were suggested for the example on page
10.
ACTIONS
- The literature will be checked
for examples (KAHOVEC).
- A letter will be written to Dr.
Fox indicating the division of the document and asking him to
propose new forms of cyclic macromolecules by 1 January, 1999
(MARÉCHAL and WILKS).
- A proposed nomenclature for rotaxanes,
polyrotaxanes, and catenanes will be provided by 31 October 1998
(WILKS).
- A further draft of the reduced
document will be prepared and sent to the WP party by 31 December
1998 (MARÉCHAL).
- The WP will send comments by 30
April 1999 (WORKING PARTY).
- A new draft will be prepared and
submitted to the Commission at the 1999 Meeting (FOX, MARÉCHAL
and WILKS).
3.9. 30/97 Polymer
Class Names
A preliminary list was
provided by Dr. Metanomski that was reviewed and discussed.
ACTIONS
- The list should be expanded to
include more classes of non-linear macromolecules (METANOMSKI).
- A selection of class names should
be defined and circulated to the WP by 31 December 1999 (METANOMSKI).
- WP to comment by 1 April 1999.
- A new version will be prepared
and circulated, by 1 June 1999, for discussion at the Berlin meeting.
3.10. 31/97 Polymerization
Processes and Polymers in Dispersed Systems
Dr. Horie, in a "short
communication" that had been circulated to the Commission, reported
cooperation with Prof. Penczek and that Prof. Slomkowski has formed
a working group to cooperate on this project.
There are 200 proposed
terms divided into groups. Deletion of the unnecessary ones was suggested
(about one fourth of the total).
After some general discussion
and Prof. Penczek's suggestion, it was decided to invite Prof. Slomkowski,
as an observer, during the Berlin meeting so that he can present his
opinions and get a feeling for our work. Also, Prof. Kubisa should
join the WP.
ACTIONS
- Prof. Slomkowski should be asked
to produce a list of terms for the WP and have it circulated by
the end of November 1998 (KUBISA).
- Comments made by the 31 January,
1999 (WP).
- Definitions should be proposed
by 31, May 1999, and circulated to the WP and the Commission for
comments and discussion at the Berlin meeting (KUBISA and SLOMKOWSKI).
3.11. 32/97 Terminology
of the Chromatography of Polymers and Related Materials (Separations)
As this is a joint project
of Commissions IV.1 and IV.2 it does not have a Commission IV.1 number.
Prof. Hess reported that
Dr. Wilks has been included in the WP and that two e-mails were received
from Prof. Dusan Berek (Comm. IV.2) asking the members of his WP to
adopt a definite strategy for this project, in the sense that the
WP should refer to a 1995 IUPAC document on chromatography and concentrate
on techniques. Prof. Hess further indicated that Dr. Berek had not
received anything from his WP but he will, in any case, write a tentative
list of terms by the end of the year in collaboration with Dr. Berek.
Prof. Stepto then suggested
that Prof. Hess take the initiative and that Prof. Vohlidal should
help him in the preparation of the list.
Since Prof. Hatada is leaving
the WP, Dr. T. Kitayama was incorporated in his place.
ACTIONS
- The WP will be requested to contribute
a tentative list of terms by 31 December 1998 (HESS).
- Definitions will be requested for
1 April 1999 (HESS).
- A draft should be prepared and
distributed to the Commission by 1 June 1999, to be discussed
at the Berlin meeting (HESS).
- Since this project has no Comm.
IV.1 number, it might be launched and adopted as a nomenclature
project. This position should be clarified with Profs. Berek and
Gilbert before the Berlin meeting (STEPTO).
4. Feasibility studies
4.1. F-6 Thermal
Properties
Prof. Shibaev reported
that the document was first seen in Guildford and then discussed in
Seoul. Six letters of support have been circulated and three additional
ones were received afterwards. Dr. Wilks added eleven more letters
from DuPont and read some of the supporting texts.
Prof. Hemminger questioned
the inclusion of terms on Definitions relating to Thermal Analysis
and suggested eliminating some of them. The WP believes that the questioned
terms are needed because they are of a general nature.
Prof. Stepto reminded the
Commission that Prof. Gilbert wanted this to be a Division project.
The Commission agreed to it. The Commission also agreed to the inclusion
of terms from the ICTA and to invite Dr. F. W. Wilburn, of the ICTA,
to join the WP.
ACTIONS
- Dr. F. W. Wilburn is to be invited
to join the WP (SHIBAEV).
- Put together all the letters of
support (SHIBAEV).
- Prof. Hemminger will be contacted
to sort out collaboration with him and to clarify matters (STEPTO
and HESS).
- The present text will be modified
and sent to Prof. Stepto giving appropriate reasons for launching
the project (SHIBAEV).
4.2. F-13 - Gel Terminology
See 3.6, project 27/95
4.3. F-15 - Functionalization
of Polymers
Prof. Horie reported essentially
on the contents of a letter of 29 June 1998, which had been sent to
the WP. The WP had concluded that the document can be divided into
two parts: functionalization and functions. Definitions should
be referenced and made self-consistent. Chemical reactions, because
they are self-evident they are not always defined but there are references
to them that Dr. Kahovec will try to provide.
Specific proposals were:
to use chlorosulfonation and not sulfochlorination, to define amination,
to remove chlorination, bromination and iodination; to include a general
statement of dereactions; to accept nitration; to change section titles
and to delete some terms.
ACTIONS
- A modified list of terms will be
sent to the WP by 31 August 1998 (HORIE).
- Comments to Prof. Horie by 31 October
1998 (WP).
- Obtain letters of support for a
project. (HORIE).
- Start work on definitions by 1
November, 1998 (WP).
- Definitions to Prof. Horie by 31
March 1999 (WP).
- Circulate a draft to the Commission
by 30 June for discussion in the Berlin meeting (HORIE).
4.4 F-16 - Terminology
of Ion-Containing Polymers
Prof. Kubisa reported that
there is a preliminary list of terms and he has received comments.
The difficulty resides in the scope of the document because it refers
to basic ionic terms. He suggested that the way to overcome the problem
was to choose fifty terms by 30 September 1998 to fix the scope of
the project.
Prof. Kubisa expressed
his concern about the inclusion of inorganic terms, because many minerals
are ion containing. Prof. Penczek suggested that some will have to
be included such as polypyrophosphates.
Prof. Kubisa indicated
that he has a complete set of terms without inorganics.
Dr. Work asked if electroconducting
(doped) polymers will be considered.
Prof. Stepto and Dr. Metanomski
requested that somebody contact the Inorganic Nomenclature Commission.
Prof. Jones offered to try to do this and come back with ideas and
suggestions.
ACTIONS
- Parallel contacts will be made
with the Inorganic Nomenclatures Commission and with Dr. M. Turner
on ion countering polymers (JONES).
- Work on a combined list of some
50 only organic basic terms and send it to the Commission by 1
October 1998 (KUBISA).
- Comments to Prof. Kubisa by 31
December 1998 (COMMISSION).
- Prepare definitions on the revised
list and send to Prof. Stepto the necessary material for Project
Initiation (letters of support, list of terms and scope of document)
by 1 June 1999 (KUBISA).
- Circulate first draft to the Commission
for discussion at the Berlin meeting by 1 July 1999 (KUBISA).
4.5 F-17 - Terminology
of Dielectric Properties of Polymers
Prof. Barón described
the situation at present. There is a long preliminary list that has
been examined by DuPont experts, was circulated to the members of
The Dielectric Society (UK) and to Prof. G. W. Bak of the Institute
of Physics, Technical University of Lodz (Lodz, Poland). He agreed
to have comments on the list after the Conference on Dielectrics and
Related Phenomena (DPR'98) to be held in Bielsko-Biala, Poland from
24 to 27 September, 1998.
Dr. Wilks offered to suggest
names of experts.
Prof. Stepto pointed out
the absence of specific terms related to polymers.
Prof. Hess indicated that
he has received many opinions of polymer people that expressed concern
over the fact that they do not know exactly what they are measuring.
Experts in non-polymeric
dielectrics should be consulted on the problem of defining what it
is exactly that the electric perturbation causes in a material.
ACTIONS
- Suggestions of terms relating to
polymers should be sent to Prof. Barón by 31 December 1998
(COMMISSION).
- Consider the inclusion of mechanical
properties related to dielectric behaviour (BARÓN).
- Prepare a new list for the Berlin
meeting (BARÓN).
- Get more supporting letters (BARÓN).
- Get the names of non-polymeric
experts by 31 December 1998 (BARÓN).
5. New Feasibility
Studies
5.1. F-18 - Ultimate
Mechanical Properties of Polymers
Dr. Work proposed this
project since it should cover the terms that could not be included
in the document on non-ultimate mechanical properties and there seems
to be a need for them. Dr. Wilks offered to get DuPont expertise on
the subject and a list of names for letters of support.
The WP will be coordinated
by Prof. Hess with the cooperation of Prof. Stepto and Dr. Work.
ACTIONS
- Review and prepare a list of terms
by 31 December 1998 (HESS, WILKS and WORK).
- Circulate to the Commission for
discussion in the Berlin meeting (HESS).
5.2. F-19 - Source
based Nomenclature for Modified Polymer Molecules
Prof. Maréchal and
Dr. Wilks consider this to be a very important project for industry
and Dr. Wilks agrees to spearhead it looking also at monographs on
polymer modifications.
The WP will be coordinated
by Dr. Wilks and will include Prof. Maréchal, Prof. Horie,
Dr. Kahovec and Prof. Vohlidal.
ACTIONS
- Send a provisional draft to the
WP by 1 November, 1998 (WILKS).
- Obtain letters of support (WILKS).
- WP to report back to Dr. Wilks
by 15 January, 1999 (WP).
- A revised version for discussion
in Berlin should be sent to the Commission by 1 June 1999 (WILKS).
- The letters of support to be sent
to Prof. Stepto (WILKS).
5.3. F-20 - Nomenclature
of Threaded Cyclic Molecules
This feasibility study
results form the separation of the subjects in Project 29/97, as discussed
above.
The WP will be coordinated
by Dr. Wilks and will include Dr. Kahovec, Prof. Kubisa, Prof. Maréchal,
Dr. Metanomski and Prof. Stepto.
ACTIONS
- Prepare and send a provisional
draft to the WP by 1 November, 1998 (WILKS).
- Obtain letters of support (WILKS).
- WP to report back to Dr. Wilks
by 15 January, 1999.
- A revised version for discussion
in Berlin should be sent to the Commission by 1 June, 1999 (WILKS).
- The letters of support to be sent
to Prof. Stepto (WILKS).
6. Other Business
6.1. Comprehensive
List of Terms
After a short discussion
it was agreed that this project can be carried out directly without
any preliminary steps. Dr. Work agreed to take care of it.
ACTIONS
- A list will be prepared in hard
copy and sent to the Commission (WORK).
- The Commission will review progress
at the Berlin meeting.
6.2. The Purple Book
Prof. Stepto asked about
a new edition. Dr. Metanomski answered that the situation is rather
similar to that of the Guide since we are actually waiting for two
documents to be completed that will become chapters: Liquid Crystals
and Regular Single Strand Nomenclature. Since they are expected to
be completed by this time next year, it will then be possible to start
the formal work as a project by writing the preface.
The WP will be coordinated
by Dr. Metanomski and will include Prof. Stepto and Dr. Work.
Dr. Work will start along
the lines of the letter written to the acting publication secretary
after last year's Meeting. The new edition of the Purple Book will
include all documents published since 1991 (eight documents) and the
Revision of Regular, Single Strand Nomenclature and Liquid Crystals
Generic Nomenclature and Polymer Class Names would probably not be
included. The question of whether or not to include the publications
of the IUBMB remains unresolved, but will be kept open as indicated
below. Especially since the letter sent by Prof. Barón to Dr.
Barry Whyte went unanswered, but a direct communication from IUBMB
has been received.
ACTIONS
- Dr. Metanomski will start with
the project
- The publisher will be contacted
again to indicate the present state of the matter (METANOMSKI).
6.3. IUBMB
Dr. Kahovec reported that
there are very few points of interest in the document received from
IUBMB. Dr. Dixon will be requested to provide an updated list of their
documents (BARÓN).
It was resolved that Dr.
Kurt Loening will continue representing Commission IV,1, although
it is understood that he can only attend meetings that are held in
the U. S. A. He will be informed of this decision (BARÓN).
6.4 Publicity.
Last year's actions regarding
the list of valid publications and publications editors, the ACS and
the European Polymer Federation will be repeated. Chemistry International
will also be contacted (BARÓN and STEPTO).
6.5 Website
There are essentially two
web sites. One corresponds to the Division and was established by
its Chairman, Prof. Robert Gilbert (http://alf.chem.usyd.edu.au/~gilbert/iupac.htm).
It contains a Division Statement and has a link to the site of Commission
IV.1.
The other site is that
of Commission IV.1, prepared by Dr. William J. Work and is updated
regularly regarding publications (http ://www.rohmhass.com/iupac/purpose/index.htm).
Dr. Metanomski mentioned
that the IUPAC home page contains historical, archival and publications
information (translations included). All information is listed and
linked.
Prof. Gilbert reported
the website status from the Division's point of view and asked Dr.
Work if there are keywords in our Commission's website. He suggested
that some be introduced. Furthermore it is very important to start
placing all documents on the web because the intention is to go electronic
on all matters (See item 5.4). Copyright matters will be taken care
of regarding the website.
Since the Purple Book is
not in electronic form, Division money may be requested to scan in
the Purple Book and create a version that can be updated whenever
pertinent. Dr. Wilks offered to cooperate.
It is the Commission's
opinion that the website should be on an easily accessible server.
It accepted Dr. Work's offer to continue taking care of the site.
Therefore, all material should be sent electronically to him.
Finally, the need for a
comprehensive list of all terms related to polymers was acknowledged
and it was decided to prepare one but not as a project. This will
not become a Project but will just be an additional Commission Activity
(WORK) and once completed will go on the web.
6.6 Documents under
Public Review
The Commission requested
that Prof. Gilbert makes a formal recommendation to the IUPAC Bureau
to make documents under public review available to National Chemical
Societies, because such societies are not in all cases the National
Adhering Organizations and documents at this stage do not reach them.
(ACTION: Prof. GILBERT).
7. Titular Members'
Meeting
Meeting in a closed session,
the titular members discussed the Commission's situation in view of
the termination of several terms of membership at the end of 1999.
The first case to be considered was that of the chairman since Prof.
Stepto ceases both as Titular Member and Chairman. After a careful
analysis it was resolved that Prof. Michael Hess should be nominated
at the Berlin meeting.
The terms of Drs. Jaroslav
Kahovec and V. M. Metanomski as Titular Members will also finish,
so it was decided to nominate Prof. Przemyslaw Kubisa and Drs. Ingrid
Meisel and Edward S. Wilks as Titular Members at the Berlin meeting.
It was further resolved
that Prof. Richard G. Jones be renominated as Pool Titular Member
at the Berlin meeting, with Dr. Meisel's Titular Membership being
subject to Dr. Jones' Pool Titular Membership continuing.
It was resolved to nominate
Prof. Jirí Vohlidal, T. Kitayama and Dr. Graham Swift as Associate
Members at the Berlin meeting.
1999 Meeting Location
The Commission will meet
for four days during the Berlin General Assembly in accordance with
the resolution at the Geneva General Assembly. An extra day will be
devoted to Division business. The Commission Officers will take the
necessary steps to implement this decision at the IUPAC Secretariat
level.
