Abstract
Stable aqueous emulsions of acrylate polymers, methacrylate polymers or butadiene polymers, which are prepared by emulsion polymerization in the presence of hydrolyzed vinyl acetate-alkali metal olefinsulfonate copolymer as an emulsifier. The aqueous emulsions thus prepared have excellent properties in storage stability, viscosity stability, dilution stability, freeze-thaw stability and miscibility with pigment or urea resin. The emulsion can also give a film excellent in water-resistance.
