BIODEGRADABLE RESIN COMPOSITIONS AND MOLDED OBJECTS THEREOF

摘要

A resin composition and a molded object which are excellent in impact resistance, tensile properties, and transparency or a resin composition and a molded object which have improved processability and heat resistance. A biodegradable polymer derived from a plant which has positively immobilized global carbon dioxide is used for these. One of the resin compositions comprises (A) a biodegradable aliphatic polyester polymer and (B) at least one copolymer selected from the group consisting of a composite rubber graft copolymer (b1) and a core-shell graft copolymer (b2). The other resin composition comprises (A) a biodegradable aliphatic polyester polymer and (C) at least one compound selected from the group consisting of a sorbitol compound (c1) having a specific structure and a substituted urea compound (c2) having a urea bond.
