    Abstract: There is disclosed an aqueous emulsion copolymer which provides an alkali-soluble anionic copolymer providing antisettling and antisag thickening characteristics especially useful in textured latex paints. The copolymers comprise an aqueous emulsion copolymer of: (A) about 10-60 weight percent of an alpha, beta-monoethylenically unsaturated carboxylic acid; (B) about 20-80 weight percent of a non-reactive monoethylenically unsaturated monomer which provides a water-insoluble copolymer; (C) about 0.5-40 weight percent of a monoethylenically unsaturated, hydrophobic nonionic monomer which is the reaction product of a monohydric or monoamine-terminated polypropoxylated or polybutoxylated hydrophobe with a monoethylenically unsaturated monomer having a single group which is reactive under the conditions employed; and (D) from 0 up to about 2 weight percent of a polyethylenically unsaturated monomer.
