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.
The present invention relates to
a resin composition
which comprises
(A), an aliphatic polyester type biodegradable polymer and
(B) at least one copolymer selected from the group consisting of composite rubber graft copolymers (b1) and core-shell type graft copolymers (b2); or,
a resin composition
which comprises
(A) an aliphatic polyester type biodegradable polymer and
(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).
