Synthesis and Characterization of Linear and Star-shaped Poly(ε-caprolactone)
摘要
Abstract
Linear poly(ε-caprolactone)(PCL)and four-arm star-shaped poly(ε-caprolactone)(S-(PCL)4)were prepared by ring-o-pening polymerization(ROP)of ε-caprolactone initiated by benzyl alcohol and pentaerythritol respectively,using stannous octoate Sn(Oct)2 as a catalyst.The structure of the polymers were characterized by 1 H NMR spectra and their molecular weight were determined by gel permeation chromatography(GPC).Linear poly(ε-caprolactone)and four-arm star-shaped polymers(ε-caprolactone)can be used to prepare am-phiphilic block copolymers based on polycaprolactone,which lays a foundation for the development and application of biodegradable drug deliv-ery carriers.关键词
