ABSTRACT:
Stable emulsions of terpolymer particles are formed by polymerizing ethylene, a vinyl ester monomer such as vinyl acetate, 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-vinyl ester-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.
