The synthesis of a new macroinitiator for cationic polymerization via radical polymerization is presented. The macroinitiator, consisting of poly(methyl methacrylate)‐ block ‐poly[styrene‐ co ‐(4‐chloromethylstyrene)], was synthesized by heating poly(methyl methacrylate), prepared in the presence of 1,1‐diphenylethylene, in a mixture of styrene and 4‐chloromethylstyrene to 85°C without any additional initiator. The resulting macroinitiator could be used for the cationic polymerization of isobutylene yielding graft copolymers.
