Polymer latices and paint formulations

Abstract From the Canadian patent

Aqueous polymer emulsions suitable for preparation of high wet adhesion latex paints comprise an emulsified film-forming copolymer of a first, hard monomer such as styrene a second, soft monomer such as butyl acrylate a wet adhesion, monomer and an acidic copolymerizable dry-adhesion promoter the, copolymer having a minimum film forming temperature of about 25°C. The emulsions are prepared by free radical polymerizations, in latex, by procedures specially adapted to avoid mutual neutralization of the monomers prior to polymerization.
