ALIPHATIC POLYESTER COMPOSITION AND ITS MOLDED ITEM

摘要

PROBLEM TO BE SOLVED: To obtain an aliphatic polyester composition having sufficiently high impact resistance and exhibiting sufficiently suppressed thermal deterioration at the time of a heat treatment enough to assure excellent durability, and a molded item obtained by melt molding the same. SOLUTION: The aliphatic polyester composition comprises an aliphatic polyester, an unmodified natural rubber and an epoxidized natural rubber, where the total content of the unmodified natural rubber and the epoxidized natural rubber in the composition is 1-30 wt% and the content of the epoxidized natural rubber in the total amount of the unmodified natural rubber and the epoxidized natural rubber is 0.5-20 wt%.
