BIODEGRADABLE MATERIAL AND METHOD FOR PRODUCING BIODEGRADABLE MATERIAL

摘要

The present invention aims to provide a biodegradable material having an improved biodegradability, an enhanced shape recovery rate after deformation of the material and an improved flexibility. The present invention provides a biodegradable material which is a chemically cross-linked product of: a multivalent compound A having 3 or more functional groups X such as hydroxyl group; a multivalent compound B having 3 or more functional groups Y such as carboxyl group; and a compound C having a structure originated from a hydroxycarboxylic acid whose homopolymer formed by homopolymerization has a glass transition point of -40°C or lower.
