PROBLEM TO BE SOLVED: To provide a polymer resin composition that is biodegradable and has been confirmed to have bioabsorbability, and has toughness, flexibility and impact resistance characteristics, and also has ductility and shape set like metal. To provide a novel material and a method for producing the same that have the same properties (can be maintained in a desired shape). (1) Biodegradable absorbent polymer having a glass transition temperature of 40 ° C. or higher and comprising a (co) polymer containing lactide or glycolide, and 50.0 to 99.9% by weight, and (2) glass transition temperature. It is less than 40 ° C. and contains 50.0 to 0.1% by weight of a biodegradable random copolymer containing lactide (or glycolide) and at least one of caprolactone, (trimethylene) carbonate, dioxanone, and lactone. A resin composition. [Selection figure] None |
