摘　　要：The halogen-terminated polymers （PS—X） were obtained by living free radical polymerization. Through the end-group transformation action of AgClO4, poly（styrene-b-2-methyl-2-oxazoline） block copolymer [P（s-b-Me-OXZ）] was synthesized by transforming the living free radical polymerization into ring-opening polymerization of 2-methyl-2-oxazoline.The obtained copolymers were characterized by SEC, IR and 1H NMR. The suitable polymerization conditions for block copolymer synthesis were studied.The halogen-terminated polymers (PS—X) were obtained by living free radical polymerization.
