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.
本发明的问题是提供一种无水溶性(吸湿性)、但具有可模塑性、优异的水分解性和生物降解性的新型可生物降解聚合物、其生产方法、其模塑产品及其应用。本发明的生物可降解聚合物是一种在分子中具有一个或多个亚胺键的生物可降解聚合物,其特征在于亚胺键构成生物可降解聚合物主链结构的一部分。可生物降解聚合物最好包括一个可生物降解单元和一个具有一个或多个亚胺键的亚胺单元,并具有可生物降解单元通过亚胺单元连接的化学结构。
