The graft copolymerizations of ethyl acrylate (A) with ethyl methacrylate (E) and butyl methacrylate (B) via redox initiation with cerium(IV) in water at 30°C are described. The kinetic parameters of the grafting reaction such as yield of the graft copolymer, grafting efficiency and total conversion were evaluated comparatively and the microstructures of the graft copolymers were analysed by l ac n.m.r, spectroscopy. The results obtained are compared with the microstructural characteristics of statistical A-E and A-B copolymers prepared by free radical copolymerization at low conversion using 2,2'-azobisisobutyronitrile as the initiator at 60c'C
