Abstract
A biodegradable material has an improved biodegradability, an enhanced shape recovery rate after deformation of the material and an improved flexibility. The biodegradable material 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.
