The present invention has its object to provide a resin composition excellent in impact resistance, tensile properties and transparency using a plant-derived biodegradable polymer obtained by positive fixation of carbon dioxide on the earth and, moldings thereof, and, further, provide a resin composition and moldings thereof improved in processability and thermal stability. n The present invention relates to na resin composition nwhich comprises n(A), an aliphatic polyester type biodegradable polymer and n(B) at least one copolymer selected from the group consisting of composite rubber graft copolymers (b1) and core-shell type graft copolymers (b2); or, n na resin composition nwhich comprises n(A) an aliphatic polyester type biodegradable polymer and n(C) at least one compound selected from the group consisting of sorbitol compounds (c1) having a particular chemical structure and urea bond-containing substituted urea compounds (c2). |
