PROBLEM TO BE SOLVED: To provide a molded product of a high-molecular aliphatic polyester- based biodegradable resin, capable of being industrially supplied and having practical properties. SOLUTION: This molded product is obtained by molding an aliphatic polyester-based biodegradable resin composition comprising an aliphatic polyester copolymer (a) having the molecular chain obtained by linking low-molecular polyester copolymers consisting of repeating units (P) represented by the formula (1): -(-CO-R<1> -COO-R<2> -O-)- (R<1> is a 1-12C divalent aliphatic group; and R<2> is a 2-12C divalent aliphatic group), and repeating units (Q) represented by the formula (2): -(-CO-R<3> -O-)- (R<3> is a 1-10C divalent aliphatic group), and having 25,000 weight average molecular weight, by an isocyanate or the like, and having >=40,000 weight average molecular weight, or the aliphatic polyester copolymer (a) and other biodegradable resin (b). |
