Abstract

Polymers are disclosed which comprise: PA0 (A) about 1-99.9 weight percent of one or more alpha, beta-monoethylenically unsaturated carboxylic acids, typically methacrylic acids; PA0 (B) about 0-98.9 weight percent of one or more monoethylenically unsaturated monomers, typically ethyl acrylate; PA0 (C) about 0.1-99 weight percent of one or more monoethylenically unsaturated macromonomers, and PA0 (D) about 0-20 weight percent or greater of one or more polyethylenically unsaturated monomers. These polymers can be solubilized in water with the aid of an alkali, like ammonium hydroxide. When the polymers are added to latex paints and neutralized, the viscosity of the paint is increased, brush drag is increased, and the paint rheology is otherwise improved.
