PROBLEM TO BE SOLVED : To provide a composition produced by mixing a biodegradable polymer derived from vegetable to a polyolefin and a molded article of the composition, and to provide a composition and a molded article of the composition having improved dispersion state of the polyolefin and the biodegradable polymer and well-balanced physical properties such as impact resistance and flexural modulus, wherein the biodegradable polymer is produced by positive fixing of carbon dioxide on earth and the composition and molded article are effective as a prevention of global warming and "carbon neutral".
SOLUTION : The composition and its molded article having well-balanced physical properties such as workability, impact resistance and elastic modulus are provided, by using a polyolefin containing an acid- or epoxy-group when mixing a biodegradable aliphatic polyester polymer to the polyolefin, wherein the composition has a dispersed structure in which the polyolefin forms the matrix, the biodegradable aliphatic polyester polymer forms the domain, and the polyolefin containing an acid- or epoxy-group encircles around the domain.
