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 suitable polymerization conditions for block copolymer synthesis were studied.
