摘要： 以聚乙二醇甲基丙烯酸酯(PEGMA)为大分子引发剂进行ε-己内酯的酶催化开环聚合, 合成出嵌段共聚物, 然后将其转化成大分子引发剂型单体(Macroinimer), 最后通过原子转移自由基聚合(ATRP)制备出一种新型结构的嵌段型支化聚合物.

关键词: 自缩合乙烯基聚合, 原子转移自由基聚合, 大分子引发剂型单体, 嵌段型支化聚合物

Abstract: A novel branched block copolymer was synthesized with self-condensing vinyl polymerization(SCVP) of macroinimer, PEGMA-b-PCL-Br, via atom transfer radical polymerization(ATRP). The macro-inimer was prepared with enzyme-catalyzed ring-opening polymerization(ROP) of ε-caprolactone(ε-CL) with poly(ethylene glycol)methacrylate(PEGMA) as the initiator and esterification of the ω-hydroxyl group of the obtained PEGMA-PCL with α-bromoisobutyryl bromide.

Key words: Self-condensing vinyl polymerization(SCVP), Atom transfer radical polymerization, Macroinimer, Branched block copolymer
