A synthetic resin emulsion containing an acetoacetylated polyvinyl alcohol as a protective colloid, which has improved properties such as water resistance, freeze-thaw stability, stability at low temperatures, adhesive property and high viscosity even in low solid content. The emulsion is useful for various purposes such as adhesive, paper treating agent, paint, fiber and textile treating agent and cement modifier.

Synthetic resin emulsion and its uses

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.
