Synthesis and Characterization of AB-Type Diblock Copolymer by Enzymatic Ring-opening Polymerization and ATRP

SHA Ke,LI Dong-Shuang,LI Ya-Peng,LIU Xiao-Tian,AI Peng,WANG Wei,WANG Jing-Yuan~(*)(Alan G.MacDiarmid Institute,College of Chemistry,Jilin University,Changchun 130023,China)  
Mono-hydroxyl terminated polycaprolactone(PCL) was prepared by Novozyme 435 catalyzed ring-opening polymerization(ROP) of ε-caprolactone(ε-CL) initiated by methanol,and subsequently converted to bromine ended PCL by the esterification of the resulting macromolecules with α-bromopropionyl bromide.The macroinitiators containing α-bromoester group were employed in the atom transfer radical polymerization(ATRP) of glycidyl methacrylate(GMA) with CuCl/2,2-bipyridine(bpy) as the catalyst system to obtain amphiphilic diblock copolymer PCL-b-PGMA.
