ABSTRACT:
The problem of the invention is to provide a novel biodegradable polymer without water solubility (hygroscopicity), but with moldability and excellent water disintegratability and biodegradability, a production method thereof, a molded product thereof and applications thereof. The biodegradable polymer of the invention is a biodegradable polymer having one or more imine bonds within a molecule, characterized in that the imine bond constitutes part of a main chain structure of the biodegradable polymer. The biodegradable polymer preferably comprises a biodegradable unit and an imine unit having one or more imine bonds and has a chemical structure, in which the biodegradable units are linked by the imine unit.
