✦ Synopsis
Photoinitiators recently developed for UV curing of pigmented ®nishes have been used to accelerate the grafting of a typical acrylate monomer, methyl methacrylate (MMA), to a variety of backbone polymers, cellulose, wool and polypropylene (PPE). Both UV and g-radiation sources have been used to initiate reaction. Novel charge-transfer (CT) monomer complexes involving electron rich donors (D) and electron poor acceptors (A) have also been used as additives in these reactions. The DA complexes themselves have been directly grafted to cellulose to produce unique copolymers. Mechanisms for the above grafting processes are proposed. The signi®cance of this grafting work in analogous radiation curing is discussed.
