    摘要: 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 α,β-unsaturated carboxylic acids, for example, a polymerizable material containing α,β-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 α,β-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 α,β-unsaturated carboxylic acids, the concentration of a cross-linking agent and a polymerization temperature during polymerization.

    摘要: In manufacturing of a carboxyl group-containing water-soluble polymer by a precipitation polymerization method, a method which can improve production efficiency with increasing practicality continuously adds a monomer solution wherein a monomer component containing an α, β-unsaturated carboxylic acid is dissolved in an inert solvent in a concentration of 20 to 50% by volume to an inert solvent charged in a reaction vessel. In this case, the amount of the inert solvent charged in the reaction vessel is set so that the concentration of the monomer component in the total amount summed up with the monomer solution is 10 to 24% by volume, and the time period until completion of continuous addition of the total amount of the monomer solution is set so that the conversion of the monomer component at the time of completion of addition of the total amount of the monomer solution is 60% or more. The monomer component may contain a polymerizable compound having two or more ethylenically unsaturated groups.

    摘要: The present invention provide a water-soluble copolymer having alkyl-modified carboxyl groups which is able to produce a neutralized viscous liquid in which although its viscosity is very low when no electrolyte exists, the viscosity greatly increases when electrolytes are added, which has a sufficiently high viscosity and a very high transmittance and which has moist textures without stickiness even in the presence of a relatively high concentration of electrolytes, and a thickening agent comprising the same. More specifically, the present invention proves a water-soluble copolymer having alkyl-modified carboxyl groups which is obtained by polymerizing 100 parts by weight of (meth)acrylic acid, 5-10 parts by weight of lauryl (meth)acrylate, and 0-0.1 parts by weight of a compound having two or more of ethylenic unsaturated groups, wherein a 1 weight %-neutralized viscous liquid shows a viscosity of 1000 mPa·s or lower and a transmittance of 95 % or higher, and when 1-7 parts by weight of sodium chloride is added to 100 parts by weight of the neutralized viscous liquid, the liquid shows a highest viscosity of 10000-30000 mPa·s and a transmittance of 95 % or higher, and a thickening agent comprising the same.
