| 英文摘要 | A biodegradable ABBA block copolymer was synthesized via the ring-opening co-polymerization of E-caprolactone (CL, B) and glycolide (A) by means of step polymerization in the presence of ethylene glycol as an initiator and stannous octanoate as a catalyst at 110 degrees C for 48 h. The molecular length of the PCL prepolymer (BB) could be adjusted by controlling the molar ratio of the ethylene glycol initiator to c-caprolactone monomer. The structure and the composition of the block copolymer were determined by the weight ratio of the monomer glycolide (A) to PCL pre-polymer (BB). The block copolymers were characterized by H-1 NMR. GPC, DSC and X-ray. The results confirm the successful synthesis of an ABBA block copolymer. |
