Abstract of the Invention Acrylic emulsion copolymers are prepared by emulsion polymerization of (A) a surfactant monomer, (B) an ?,.beta.-ethylenically unsatruated carboxylic acid monomer, (C) a nonionic ?,.beta.-ethyenically unsaturated monomer and (D) optionallly a polyethylenically unsaturated cross-linking monomer. The surfactant monomer is prepared by condensing a mono or polyhydric alcohol nonionic surfactant with methylene succinic acid. At a low pH the copolymer may be in the form of an aqueous dispersion or latex, but thickens upon neutralization of at least some of the carboxyl groups. The resulting copolymer dispersions which contain 5 to 50 percent, generally 20 to 40 percent of copolymer, are suitable as is for use in various industrial applications such as adhesives, coatings, drilling fluids, cleaners, walljoint compounds, lotions and other personal care products, highly absorbant applications, paints, wall paper adhesives, textile print pastes, textile sizings, oil recovery applications, and the like.
