Abstract

Abstract: The group transfer block copolymerization of methacrylates and acrylates with bifunctional initiators and benzoate catalyst was reported.ABA-triblock copolymers of MMAand BA, MMAand BMA, MMAand EM Awith predetermined molecular weight and low polydispersity were obtained.When copolymerizations of different kinds of methacrylates were carried out, the monomer with larger steric hindrance must be used as the first monomer; when copolymerizations of methacrylate and aery-late were carred out, methacrylate must be used as the first monomer.The copolymers were characterized by ¹H NMR, GPCand DSC.

Key words: Group transfer polymerization, Block copolymerization, Bif unctional initiator
