description PROBLEM TO BE SOLVED: To provide a biodegradable plastic raw material capable of ensuring long-term reliability, particularly, a biodegradable polyester raw material, and a molding originated from the biodegradable plastic raw material. SOLUTION: In the biodegradable plastic raw material prepared by treating a biodegradable plastic with a compound capable of reacting with active hydrogen in the biodegradable plastic, the compound is a crosslinking agent having a carbodiimide group, comprises dicyclohexyl carbodiimide or diisopropyl carbodiimide, and is reacted with the active hydrogen till its acid value is ≤0.5. A molding thereof is also provided. COPYRIGHT: (C)2008,JPO&INPIT
