乙交酯-己内酯共聚物的功能化研究

摘要

A new type of functional copolymer,amino-terminated caprolactone-glycolide copolymer (PGCL-NH2) was synthesized from monomer glycolide and caprolactone through three-step reactions including ring-opening polymerization,adding protecting group,and removal of protecting group.The copolymer PGCL-NH2 and its intermediate products were characterized by FTIR,TGA and DSC.The result show that this synthetic route is successful,it opened up a new way for the preparation of the amino-terminated polyester copolymer.%以乙交酯和己内酯为起始原料,经开环聚合、上保护基团、脱保护基团三步反应合成了新型功能化乙交酯-己内酯共聚物,端氨基乙交酯-己内酯共聚物PGCL-NH2.采用红外光谱、DSC以及TGA对合成的共聚物及其中间产物进行了表征和分析.结果表明,此合成工艺路线是成功的,其为制备端氨基聚酯共聚物开辟了一条新途径.
