PROBLEM TO BE SOLVED: To provide a method for producing a water-absorbing polymer comprising a crosslinked naturally-derived polymer excellent in a water absorption magnification and water permeability in the water absorption state.SOLUTION: A production method of a water-absorbing polymer includes a step for irradiating a radiation to a mixture containing a 100 pts.mass naturally derived polymer, a 5-50 pts.mass polyfunctional monomer having at least two of at least one kind of reactive group selected from a group comprising a vinyl group, an allyl group, an acryloyl group and a methacryloyl group, and 5-2,000 pts.mass water. |
