Abstract: A process is disclosed for producing a carboxyl-containing polymer composition that allows the possibility of obtaining a carboxyl-containing polymer composition which exhibits excellent dispersibility in water or the like, has a viscosity increasing to a lower degree compared to the viscosity of a neutralized viscous liquid using an additive-free carboxyl-containing polymer, and has a high degree of transparency in a neutralized viscous liquid thereof. A carboxyl-containing polymer composition is obtained by polymerizing a monomer containing an ?,?-unsaturated carboxylic acid as a main component in a presence of a polyol (iso)stearic acid ester. A polyol in the polyol (iso)stearic acid ester is a polyol selected from a specific group, and the polyol (iso)stearic acid ester is used in the polymerization in an amount of 0.2 to 7 parts by mass based on 100 parts by mass of the ?,?-unsaturated carboxylic acid.

Abstract: A gelling agent capable of turning an electrolyte solution for an alkaline battery into a gel, which is less likely to cause syneresis, is composed of particles of a carboxyl group-containing polymer, and a 0.1% by weight aqueous solution has a viscosity of at least 3,000 mPa·s at a pH of 7. The particles of a carboxyl group-containing polymer are normally obtainable by polymerizing a polymerizable material containing ?,?-unsaturated carboxylic acids, for example, a polymerizable material containing ?,?-unsaturated carboxylic acids and a compound having two or more ethylenically unsaturated groups as a cross-linking agent, in an inert solvent which dissolves the ?,?-unsaturated carboxylic acids but does not dissolve particles of a carboxyl group-containing polymer. The above-mentioned viscosity is achieved by adjusting the balance among the concentration of the ?,?-unsaturated carboxylic acids, the concentration of a cross-linking agent and a polymerization temperature during polymerization.

Abstract: The present invention is concerned with a high water-absorbent resin composition, produced by forming a composite by fusing or fixing a thermoplastic resin onto a surface of a high water-absorbent resin via an adhesive binder or directly, wherein the composition comprises from 1 to 100 parts by weight of the thermoplastic resin, based on 100 parts by weight of the high water-absorbent resin.When the high water-absorbent resin composition of the present invention is used, it is possible to securely adhere a high water-absorbent resin to a fibrous base material, so that a water-absorbent material which stably retains the high water-absorbent resin even after absorbing water can be obtained. Accordingly, the base materials, such as fibrous base materials, can retain more amount of high water-absorbent resin than those of conventional water-absorbent materials.

Abstract: Water-swellable elastomer composition consisting essentially of a homogeneous mixture of an elastomer, a water-absorbent resin and a water-soluble resin. Said composition exhibits a high degree of swelling and a high swelling rate when it is soaked in water. Also, said composition retains swellability even when it is put in contact with water for a long period of time.
