摘要： A water-absorbent resin is produced by dispersing a solid blowing agent having an average particle diameter within a range of from 1 &mgr;m to 100 &mgr;m in an aqueous monomer solution containing an unsaturated monomer and a cross-linking agent, and then polymerizing the unsaturated monomer. The water-absorbent resin has excellent water absorption characteristics, such as improved dispersion and absorption rate of aqueous fluid, enhanced water retention capacity and dry touch, lower water-soluble component content, and lower residual monomer content. When a water-absorbent resin composition using the water-absorbent resin is used for, for example, a sanitary material, it is possible to improve the absorption rate and water retention capacity, and prevent leakage of fluid from the sanitary material.

摘要： A water-absorbent resin is produced by crushing a mass of crosslinked hydrogel polymer having high adhesion and elastic properties without kneading it, and drying the crushed crosslinked hydrogel polymer. In the case when the crosslinked hydrogel polymer includes cells therein, the crosslinked hydrogel polymer is crushed so as to restrain reduction in the number of cells contained in the crosslinked hydrogel polymer. The crosslinked hydrogel polymer is crushed by any of crushing methods including: shearing the crosslinked hydrogel polymer with a fixed blade and a rotary blade; cutting the crosslinked hydrogel polymer with a cutter having a pair of rotary blades that are mounted on different shafts and rotate while at least partly overlapping each other; cutting the crosslinked hydrogel polymer with a cutter having a rotary blade using a lubricant; and crushing the crosslinked hydrogel polymer after freezing. With the use of the above methods, it is possible to industrially and easily mass-produce porous water-absorbent resins with excellent absorption properties while restraining reduction in the number of cells contained in the crosslinked hydrogel polymer.

摘要： A gelling material is composed of water-absorbent resin 12 wrapped in a bag composed of two laminated water-soluble sheets 1.1, the water-absorbent resin being prepared so as to enable the bag to be disintegrated by an inner pressure generated when an expanded volume of the water-absorbent resin by absorbing water through the bag exceeds a maximum volume capacity. When the gelling material is added to the aqueous fluid, the water-absorbent resin 12 is spread in the aqueous fluid at a stroke, and is diffused uniformly. Thus, the water-absorbent resin 12 is brought fully in contact with the aqueous fluid. Since this enables the aqueous fluid to be gelled in a short period of time, the aqueous fluid can be processed speedily. Even the aqueous fluids, which are difficult to be handled by the conventional gelling material, can be gelled conveniently in a short period of time, and the resulting gell can be easily handled, thereby enabling an easy disposal of the aqueous fluids, i.e., the gell. Additionally, since the water-absorbent resin is spread in the aqueous fluid at a stroke, and is diffused uniformly, a troublesome operation of agitating the aqueous fluid can be eliminated during the gelling process, thereby enabling a simplified gelling process.
