Many optically active polymers have been synthesized through asymmetric
polymerization reactions from optically inactive monomers. The basic
definitions of terms relating to polymerization reactions have been
published in IUPAC documents, but no explicit reference has been
made to reactions involving the asymmetric synthesis of polymers.
As a result, several names have been used for the same type of industrially-important
asymmetric polymerization processes and this leads to confusion
and prevents a better understanding of asymmetric polymerizations.
The aim of this document is to define unified terms relating to
polymerization processes which involve chirality and which proceed
in an unsymmetrical manner under the influence of chiral features
present in monomer, initiator, catalyst and solvent.
A new draft was prepared by the Working Party after the discussion
at the Geneva meeting of the Commission in 1997 and was thoroughly
discussed at the Sydney meeting in 1998, with particular emphasis
on the consistency with organic-chemistry nomenclature and correct
English. A new version was prepared by the Working Party after consultation
with authorities on asymmetirc polymerisation. The final version
was discussed and approved in Berlin and is being sent out to Outside
Experts in September, 1999.
A revised document is submitted to public review comments until
30 April 2001
