摘要: 采用一种新型的稀土配位化合物Y(CF3COO)3/Al(i-Bu)3为催化剂,制备了不同组成的ε-己内酯/d,l-丙交酯共聚物,并用GPC、NMR和DSC表征了共聚物的结构。结果表明通过改变初始投料中两种单体的比例,可以调节共聚酯的化学结构,而共聚物的形态则受结构影响很大。

Abstract: ε-Caprolactone/d,l3COO)3 and triisobutylaluminum Al(i-Bu)3, and characterized by GPC and 1H NMR. The results show that the chemical compositions of ε-caprolactone/d,l-lactide copolymers can be adjusted by changing the monomer weight ratio in feed, and morphology of the copolymer is influenced greatly by the composition.

Key words: caprolactone/lactide copolymer, rare earth coordination, biodegradable material
