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： N-Cyclohexylmaleimide having a cyclohexylaminosuccinic anhydride content of 0.001 to 1 wt. % is used as the main raw material for the production of heat-resistant resins. The resins are produced by a process of copolymerizing the above material with at least one monomer copolymerizable therewith which is characterized by the use of a monomer having a low yellowness, the addition of a compound which can inhibit the evaporation of the non-radical compounds contained in the monomer through reactions, the addition of an antioxidant, the use of a solvent containing alcohol, or the presence of a non-radical-polymerizable acid anhydride or carboxylic acid. The heat-resistant resins produced by the use of the above raw material or the above process are excellent in transparency, i.e., less discolorable, even when an increased amount of N-cyclohexylmaleimide is used for the purpose of imparting more excellent heat resistance. Accordingly, the heat-resistant resins can be suitably used in the fields necessitating both a low discolorability and a high heat resistance.

摘要： Reversed phase suspension polymerization is allowed while controlling content of minor components in monomer, particularly controlling a content of acetic acid and propionic acid being not higher than 500 ppm, controlling a content of acrylic acid dimer being not higher than 1000 ppm, in acrylic acid. Cross-linked polymer obtained by the polymerization is subjected to a surface crosslinking treatment without substantially using an organic solvent, and under heating at high temperature (150° C. or higher and 250° C. or lower). Thereafter, agglomeration is carried out without substantially using an organic solvent. Accordingly, a particulate water-absorbing agent including a water-absorbing resin having superior property, and being suited for practical applications at high concentrations in absorbing cores such as a diaper and the like without generation of any odor of the organic solvent can be obtained because no volatile organic compound is included.
