(57) Abstract: An object of the present invention is to provide a method for granulating a highly water-absorbent resin, which is excellent in water absorption capacity and water absorption capacity under load. SOLUTION: When granulating by superposing a water-absorbent resin in the coexistence of a cross-linking agent, a water-insoluble inorganic powder and water, water is further added at the time of temperature rise and / or during the cross-linking reaction to obtain high water absorption. To obtain a granule of the functional resin. |
