The photoinitiated free‐radical polymerization of methyl methacrylate (MMA) and the radical‐promoted cationic polymerization of cyclohexene oxide (CHO) in the presence of low‐molecular‐weight polyepichlorohydrin terminated with groups containing benzoin derivatives were studied. Benzoin‐terminated polyepichlorohydrin was prepared by Activated Monomer (AM) polymerization. Upon photolysis. polymer‐bound alkoxy benzyl radicals were generated, initiating the radical polymerization of MMA. In the case of radical‐promoted cationic polymerization of CHO, the cationic initiating species were formed by the oxidation of photochemically generated polymeric radicals by N‐ethoxy‐2‐methylpyridinium hexafluorophosphate.
