摘　　要：聚苯乙烯接枝聚甲基丙烯酸甲酯共聚物的合成新方法①郭金全邹友思戴李宗袁亿文潘容华（厦门大学化学系厦门３６１００５）阴离子聚合［１］和基团转移聚合（ＧＴＰ）［２］技术可分别使非极性单体和极性单体进行活性聚合，得到分子量分布窄、实际分子量和设计分子量相近的...Polystyrene g polymethylmethacrylate with controlled molecular weight and lower polydispersity was obtained by using anionic polymerization, group transfer polymerization (GTP) and polymer reaction. First, NDPS (PS with narrow n distribution) prepared by anionic polymerization was chloromethylated by methylal and sulfurylchloride to form chloromethylation polystyrene (CMPS); and then, CMPS dissloved in THF whose impurity was removed by sodium naphthalene, coupled with living polymer of PMMA prepared by GTP. The copolymer was characterized by 1HNMR. FT IR and GPC. The n and D of copolymers were 1×10 4～3×10 4 and 1.08～1.20 respectively.
