Abstract

PURPOSE: To provide a thickener free from the tendency of separating water from its surface and having excellent water retention, and composed of an emulsion obtained by the emulsion polymerization of a monomer mixture containing methacrylic acid in high concentration and a specific amount of a monomer having a polymerizable double bond.
CONSTITUTION: The objective thickener is composed of an emulsion obtained by the emulsion polymerization (using preferably polyoxyethylene alkylsulfuric acid ester salt as the emulsifier) of a monomer mixture containing (A) 53W75wt% methacrylic acid and (B) a monomer (preferably allyl acrylate, etc.) having two or more polymerizable double bonds, or an aqueous solution obtained by neutralizing said emulsion with an alkali (preferably neutralized with sodium hydroxide, etc. to 7W11pH). The amount of the polymerizable double bond of the component (B) is 0.001W0.005 per one carboxyl group in the whole monomers.
