摘要
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.
Mono-hydroxyl terminated polycaprolactone（PCL） was prepared by Novozyme 435 catalyzed ringopening polymerization（ROP） of 6-eaprolaetone（ε-CL） initiated by methanol, and subsequently converted to bromine ended PCL by the esterifieation of the resulting macromoleeules with α-bromopropionyl bromide. The maeroinitiators containing ,α-bromoester group were employed in the atom transfer radical polymerization （ ATRP） of glyeidyl methaerylate（GMA） with CUE1/2,2-bipyridine（bpy） as the catalyst system to obtain amphiphilie diblock eopolymer PCL-b-PGMA.
