for Radical Polymerizations with Minimal Termination
10 years ago it was discovered that the addition of certain
compounds—e.g., nitroxides or complexes of Cu(I)—had
a profound effect on the course of a radical polymerization.
The radicals formed are then able to persist for long periods,
consequently the molecular weight of the polymer produced
increases with conversion, resulting in low polydispersity.
In their enthusiasm for novel reactions of this kind, the
authors of papers describing their results developed individual
types of nomenclature without any coordination.
frenzy of activity on the part of individuals outside IUPAC
to attempt to define terms, or to call for regulated terminology,
demonstrates the urgent need for an appropriate IUPAC body
to quickly provide an internationally agreed set of terms
in this field of the so-called "living" and/or "controlled"
radical polymerization. The IUPAC Subcommittee on Macromolecular
Terminology wishes to resolve these issues with a minimum
