Poly(vinyl acetate)-b-polystyrene, poly(vinyl acetate)-b-poly(methyl acrylate) and poly(vinyl acetate)-b-poly(methyl methacrylate) block copolymers with low polydispersity (M(w)/M(n) < 1.25) were prepared by successive reversible addition-fragmentation chain transfer (RAFT) polymerization and atom transfer radical polymerization (ATRP) employing a bromoxanthate iniferter (initiator-transfer agent-terminator).
采用溴代黄原酸酯引发转移终止剂（引发剂-转移剂-终止剂），通过连续的可逆加成-断裂链转移（RAFT）聚合和原子转移自由基聚合（ATRP）制备了具有低多分散性（M(w)/M(n) < 1.25）的聚（醋酸乙烯酯）-b-聚苯乙烯、聚（醋酸乙烯酯）-b-聚（丙烯酸甲酯）和聚（醋酸乙烯酯）-b-聚（甲基丙烯酸甲酯）嵌段共聚物。
