Abstract: Stable emulsions of terpolymer particles are formed by polymerizing ethylene, an acrylic monomer such as acrylic acid, and an alkyl vinyl monomer having from about 3 up to about 24 carbon atoms in an aqueous medium in the presence of a water soluble persulfate initiator, and a nonionic and/or anionic emulsifier. The resulting novel stable emulsions contain particles of ethylene-acrylic-alkyl vinyl terpolymer which will provide film coatings of increased flexibility and toughness. Furthermore, the emulsions have excellent compatibility when blended within conventional polish formulations.

Abstract: Polymer dispersions in which an aqueous phase comprising a water-soluble polymer is dispersed in an organic liquid in the presence of a polymeric water-in-oil type dispersing agent containing salt-forming basic nitrogen atoms. When the dispersion is mixed with water in the presence of an acid, which acid may be present in the aqueous or organic phase of the dispersion or added separately, the dispersing agent transforms into an oil-in-water type, the previously dispersed polymer dissolves in the water, and the previously continuous organic phase is dispersed in the water.Methods of making such polymer dispersions.Methods of forming aqueous solutions of water-soluble polymers by combining such dispersions with water in the presence of an acid.
