A water-swellable polymer gel prepared by reacting an ester of a carboxyl group-containing polysaccharide with a compound having at least two alpha -amino groups, which is derived from a natural amino acid, and a foamed article thereof. The water-swellable polymer gel can be used in the fields such as industry, agriculture, food and medicine. The applications of the water-swellable gel in the medical field include wound dressings, adhesion-preventing materials, dialysis membranes, hemostatic materials, adhesive materials, sealants, contact lenses, materials for tissue regeneration, microcapsule materials and drug delivery systems. |
