Abstract
A carboxyl group-containing polymer composition comprising 100 parts by weight of a carboxyl group-containing polymer (A) prepared by copolymerizing an α,β-unsaturated carboxylic acid (a) with a compound (b) having at least two ethylenic unsaturated groups; and 0.01 to 20 parts by weight of at least one compound (B) selected from an ester (c) obtained from a polyhydric alcohol and a fatty acid, and an alkylene oxide adduct of an ester (d) obtained from a polyhydric alcohol and a fatty acid. Since the carboxyl group-containing polymer composition is excellent in the solubility in water and gives the aqueous solution excellent thickening property, the polymer composition can be suitably used as a thickener for various aqueous solutions.
