摘要 以二硫代苯甲酸异丁腈酯为RAFT试剂,偶氮二异丁腈为引发剂,制备不同嵌段长度的甲基丙烯酸甲酯-苯乙烯嵌段聚合物。嵌段聚合物数均分子量的实验值与理论值接近,但由于RAFT聚合过程中,聚甲基丙烯酸甲酯死聚物的生成,使嵌段聚合物的分子量分布指数较宽。 The block polymerization of methyl methacrylate and styrene mediated by 2-cyanoprop-2-yl dithiobenzoate was studied using 2,2＇ -azobis （ isobutyronitrile ） as initiator. The experimental Mn of MMA-St block copolymers was closed to the theoretical M. However, the dead PMMA chains, generated in the RAFT polymerization, led to higher molecular weight distributions of MMA-St block polymers.
