Terminology for Radical Polymerizations with Minimal Termination
Terminology for Radical Polymerizations with Minimal Termination
About 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.
The 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 of delay.
