Abstract

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
