PROBLEM TO BE SOLVED: To provide a water-swellable polymer gel comprising a naturally derived component having high water absorption and gel strength and a water-swellable polymer gel foam comprising the same, and productivity. And a method for producing a water-swellable polymer gel which has high safety to the human body and can be easily produced in an aqueous solvent. A water-swellable polymer gel obtained by reacting an esterified carboxyl group-containing polysaccharide with a compound having two or more α-amino groups derived from a natural amino acid, A medical material comprising the water-swellable polymer gel, a medical material comprising the water-swellable polymer gel foam, and an esterified carboxyl group-containing polysaccharide and two α-amino groups derived from a natural amino acid A method for producing a water-swellable polymer gel, which comprises reacting the above-mentioned compound with the compound. |
