Abstract

See full text

The invention provides a carboxyl group-containing polymer composition which has excellent solubility in water and thickening property of an aqueous solution, has small viscosity change caused by a thermal history in a drying process, and is mixed with water to obtain a neutralized viscous liquid with high transparency. A carboxyl group-containing polymer composition comprising (A) a carboxyl group-containing polymer obtained by copolymerizing an alpha, beta-unsaturated carboxylic acid (a1) and a compound (a2) having at least 2 ethylenically unsaturated groups in the molecule, (B) a polyol fatty acid ester alkylene oxide adduct, and (C) a polyoxyalkylene-modified product which is at least one of an ether (C1) and a polyoxyalkylene fatty acid ester (C2) comprising an aliphatic alcohol and a polyoxyalkylene group.
