摘要：
Poly(ethylene glycol) grafted poly(L-lactide) was prepared by ring opening polymerization of L-lactide and epoxy-terminated poly(ethylene glycol) methyl ether (PEGME). Stannous octoate and Al(Et)(3). 0.5H(2)O were tested as polymerization catalysts, and Al(Et)(3). 0.5H(2)O was found to be more effective for the ring-opening of the epoxy group of the modified PEGME monomer. The synthesized polymers were characterized by NMR and the efficiency of the incorporation of epoxy-terminated PEGME in the copolymer was determined.
