英文摘要	联系人及第一作者: 邹友思, 男, 42 岁, 副教授.; [中文文摘]采用基团转移聚合、阴离子聚合以及高分子偶合反应的方法，合成了一种结构明确、链长均匀和分子量可控的聚苯乙烯接枝聚甲基丙烯酸甲酯．主链聚苯乙烯由阴离子聚合得到，并进行溴甲基化．支链活性聚甲基丙烯酸甲酯由基团转移聚合制备．经偶合反应后得到分子量为３×１０４～７×１０４、多分散性指数Ｄ为１．２～１．４的接枝共聚物．溴甲基化聚苯乙烯和活性聚甲基丙烯酸甲酯的偶合反应活性随分子量的增大而降低，理想的反应温度为－２０℃．用１ＨＮＭＲ、ＧＰＣ和ＤＳＣ表征接枝产物．和均聚物相比，共聚物的玻璃化温度较低．[英文文摘]A novel well defined graft copolymer(PS g PMMA) with control over the length of both backbone and side chain was synthesized by coupling reaction of living polymethyl methacrylate with bromomethylated polystyrene. The backbond polymer was prepared by anionic polymerization of styrene with n butyllithium followed by bromomethylation using C 8H 17 OCH 2Br/SnCl 4 . The living PMMA was prepared by group transfer polymerization of MMA. The graft copolymers with narrow molecular weight distribution,D= 1. 2～1. 4, at the Mn of around 3×104～7×104 were obtained. The reactivity of the BMPS and living PMMA decrease with increasing of their molecular weight,favorable reaction temperature was - 20 ℃. Characterizat ion o f the product include 1H NMR, 13C NMR, GPC and DSC, comparing with the homopolymer PS and PMMA, the copolymer has a lower glass temperature.; 国家自然科学基金,国家教委留学回国人员启动基金
