Abstract

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
