Abstract
A biodegradable elastomer obtained by blending a sugar polymer compound having the general formula (I) with a cross-linking agent having the general formula (II) or (III). 1 wherein, G denotes a sugar residue of which at least one hydroxyl group not participating in polymerization may be substituted with an ester group; R denotes a substituted or unsubstituted aliphatic hydrocarbon group having 4 to 16 carbons; and n denoting the polymerization degree is an integer from 1 to 5,000; m is 0 or an integer of from 1 to 12; and L is an integer of from 1 to 12.
