Zusammenfassung:	PURPOSE:To provide a biodegradable polymer produced by using konjakmannan as a main component and adding a cross-linking agent to the konjakmannan, having high water-retainability and cold-keeping property and exhibiting excellent biodegradability when discarded after the use as a cold-keeping agent, etc. CONSTITUTION:This biodegradable polymer having high water-retainability and cold-keeping property is produced by adding a proper amount of a cross- linking agent such as glutaraldehyde, formaldehyde, paraformaldehyde, trioxane and cyanuryl chloride to konjakmannan. The biodegradable polymer is used as a cold-keeping agent by putting in a container and discarded after use in a biodegradable state by taking out of the container.
