摘要： 在Novozyme 435脂肪酶催化下, 甲基丙烯酸羟乙酯(HEMA)引发己内酯(ε-CL)开环聚合反应, 得到一端为双键, 另一端为羟基的直链聚己内酯(PCL)产物; 将其端羟基官能化得到大分子AB*型单体, 与苯乙烯以原子转移自由基聚合(ATRP)反应形式进行自缩合乙烯基共聚合, 得到超支化结构聚苯乙烯-b-聚己内酯产物.

Abstract: This work was directed to develop a novel method for the synthesis of hyperbranched polymers by combining enzymatic ring-opening polymerization(ROP) with self-condensing vinyl copolymerization(SCVCP). Functionalized PCL was prepared by ROP of ε-CL with HEMA as the initiator and catalyzed by Novozyme 435, and subsequently converted to AB* macroinimer by the esterification with 2-bromoisobutyryl bromide. The target polymer was obtained by SCVCP of AB* macroinimer with styrene via ATRP.

Key words: Enzymatic ring-opening polymerization, Novozyme 435, Self-condensing vinyl copolymerization(SCVCP), Hyperbranched polymer
