Abstract:
1. An aliphatic polyester resin composition, comprising an aliphatic polyester resin (A), a monocarbodiimide compound (B) and an aromatic polycarbodiimide compound (C); wherein the aliphatic polyester resin (A) is a polylactic acid resin; wherein the aliphatic polyester resin (A) and the monocarbodiimide compound (B) in total are present in an amount of 90% by mass to 99.9% by mass and the aromatic polycarbodiimide compound (C) is present in an amount of 0.1% by mass to 10% by mass, with respect to the total amount of (A), (B) and (C); wherein the aliphatic polyester resin composition is a reaction product of the monocarbodiimide compound (B); the aromatic polycarbodiimide compound (C); and the aliphatic polyester resin (A); wherein the monocarbodiimide compound (B) is selected from the group consisting of diisopropylcarbodiimide, bis(methylphenyl)carbodiimide, bis(methoxyphenyl)carbodiimide, N-ethyl-N′-(3-dimethylaminopropyl)carbodiimide and cyclic carbodiimides; and wherein the monocarbodiimide compound (B) is present in a different amount by mass than the aromatic polycarbodiimide compound (C).
