Abstract

Styrene/N‐cyclohexylmaleimide copolymers with small polydispersities and controlled molecular weights were synthesized by a free radical copolymerization using an iniferter system consisting of benzoyl peroxide and 2,2,6,6‐tetramethylpiperidine‐N‐oxyl. Due to the interactions of the electropositive (styrene) and electronegative (N‐cyclohexylmaleimide) monomers the brutto polymerization rates are higher than for other living polymerizations initiated with the same iniferter system. The prepared copolymers were used as macroiniferters for bulk polymerization of styrene.

## Abstract Polystyrene/poly[styrene‐__co__‐(butyl methacrylate)] block copolymers with controlled molecular weights and with polydispersities generally below __M̄__~w~/__M̄__~n~ = 1,45 and partially as low as __M̄__~w~/__M̄__~n~ = 1,19 were synthesized by a free radical bulk copolymerization using
