✦ Synopsis

Graft copolymerization of ethyl acrylate on starch in an aqueous medium was studied at 29Β°C using various concentrations of monomer and of ceric ion as initiator. The dependence of the extent of graft polymer formation (graft level, molecular weight and number of grafted chains, and frequency of grafting) on [initiator] and [monomer] suggests that termination of graft copolymerization proceeds mainly by reaction of ceric ion with growing graft chains and that radicals formed on the polymeric substrata may not be reactive in propagation.
