Composition for producing biodegradable polyester resin, and production method for biodegradable polyester resin

摘要

Disclosed are a composition for producing biodegradable polyester resin, and a production method for biodegradable polyester resin. The disclosed composition for producing biodegradable polyester resin comprises: a dicarboxylic acid; a diol; a catalyst; and a deactivating agent comprising an element (L) able to reduce the activity of the catalyst, and, here, the content of a metal (M) in the catalyst and the content of the element (L), as a weight ratio, satisfies the following condition: 1.5 ≤ M/L ≤ 8.0.
