Abstract: 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, IRand 1H NMR. The suitable polymerization conditions for block copolymer synthesis were studied.

Key words: Living free radical polymerization, Macromolecular initiator, Poly(styrene-b-2-methyl-oxazoline), Block copolymer
