Abstract: Provided is a water-absorbent resin which is capable of giving an absorbent material improved gel-shape stability and which has excellent water-absorption capacity. A water-absorbent resin of the present invention is a polymer of a water-soluble ethylenically unsaturated monomer, and has the following properties (1) and (2): (1) A disintegration amount at 20-fold swelling is 30% by mass or less; and (2) a solubility in physiological saline is 25% by mass or less. (Determination Method for Disintegration Amount at 20-Fold Swelling) 5 g of the water-absorbent resin is added to 100 g of physiological saline to allow the water-absorbent resin to absorb the physiological saline, thereby obtaining a gel. The obtained gel is divided approximately equally into five portions, and these portions are introduced respectively into cylindrical molds having a length of 3.6 cm and a radius of 2.8 cm and molded. The masses of the five molded cylindrical gels are measured.
Abstract: A method of preparing a superabsorbent polymer, which enables the preparation of the superabsorbent polymer exhibiting an improved absorption rate while maintaining excellent absorption performances is provided.
