  • Ethylene-styrenic-alkyl vinyl terpolymer emulsions having particle size of 100 to about 100 angstrom units
    Patent number: 3974119
    Abstract: Stable emulsions of terpolymer particles are formed by polymerizing ethylene, a styrenic monomer such as styrene, 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 of the three monomers which will provide film coatings of increased flexibility and toughness. Furthermore, the emulsions have excellent compatibility when blended with conventional polish formulations.
