摘　　要：甲基丙烯酸酯的基团转移嵌段共聚研究戴李宗邹友思陈良坦潘容华（厦门大学化学系厦门３６１００５）关键词基团转移聚合，甲基丙烯酸酯，嵌段共聚物，结构表征基团转移聚合［１］（ＧｒｏｕｐＴｒａｎｓｆｅｒＰｏｌｙｍｅｒｉｚａｔｉｏｎ，ＧＴＰ）具有活性聚合的特点...Group transfer block copolymerization of methylmethacrylate (MMA) and C 7～9 methacrylate (C 7～9 MA) was studied by using 1 methoxy 1 (trimethylsiloxly) 2 methyl 1 propene (MTS) and tetrabutylammonium bibenzoate (TBABB) as initiator and catalyst respectively. The influence of temperature、/ and monomer sequence on GTP was discussed. When T =85℃, =0.16 mol/L; /=0.19±0.01, C 7～9 MA as first monomer was favorable to the synthesis of PC 7～9 MA b PMMA block copolymer. According to Arrhenius equation, the activation energy of PC 7～9 MA GTP was counted to be ( Ea =48 3 KJ/mol). The molecular weight and molecular weight distribution of copolymer were measured by GPC. The structure of block copolymer was characterized by FT IR and 1 H NMR.
