Abstract
Stable emulsions of terpolymer particles are formed by polymerizing ethylene, a vinyl halide monomer such as vinyl chloride, 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 terpolymer which will provide film coatings of increased flexibility and toughness. Furthermore, the emulsions have excellent compatibility when blended within conventional polish formulations.
