30 No. 4
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.
