Polymer Division
Subcommittee on Polymer Terminology
Dispersity
This recommendation defines just three terms, viz., molar-mass
dispersity, degree-of-polymerization dispersity, and dispersity. 'Dispersity'
is a new word, coined to replace the misleading, but widely used term
'polydispersity index'. The document, although brief, also has a broader
significance in that it seeks to put the terminology describing dispersions
of distributions of properties of polymeric (and non-polymeric) materials
on an unambiguous and justifiable footing..
