Abstract

Abstract: Chloroacetyl polystyrene macroinitiator was synthesized by anionic polymerization. The optimum conditions for the synthesis of chloroacetyl oligomer are as follows: acylating temperature is 60 ℃, acylating time is 24 h and chloroacetyl chloride is excess 5 fold for n-butyl lithium. The structure of α chloroacetyl polystyrene macroinitiator was characterized by IRand ¹H NMR. Block copolymer, such as PSt-b-PMA, PSt-B-PBA, was synthesized by ATRPwith α-chloroacetyl polystyrene oligomer as macroinitiator and the structure of PSt-b-PMAwas characterized by ¹H NMR.
