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
