Abstract: Colloid-free vinyl acetate latexes having an average particle size between 400 .ANG. to 700 .ANG. at a concentration of 30 to 50% by weight have been prepared. The latexes comprise 60 to 100 weight parts of vinyl acetate monomer with about 40 to 0 weight parts of one or more ethylenically unsaturated comonomers such that the glass transition temperature of the polymers are between -10.degree. and 40.degree. C. The latexes are prepared by emulsion polymerization in aqueous medium, in the presence of 0.05 to 20 parts of an anionic surfactant, e.g., alpha-olefin surfactant, and 0.05 to 15 parts of an ionic comonomer, e.g., sodium 2-acrylamido-2-methylpropane sulfonate (Na-AMPS). The interior wall primer-sealer derived from these fine particle size vinyl acetate latexes showed excellent enamel hold-out properties and paint stability. The latexes may also be applied aas binders in the manufacture of other paints, adhesives, papers, and as textile sizes.

Abstract: The paint coating composition comprises a cationic free, functional emulsion polymer mixture adapted to be coreacted at room temperature with glycoluril to provide a cured thermoset paint film. The process comprises copolymerizing ethylenically unsaturated monomers, including functional monomers, but excluding amine monomers, in an aqueous polymerization medium, followed by ion exchange of the resulting reactive emulsion polymer. Preferably, the glycoluril is processed through an ion exchange step separately or in conjunction with the reactive emulsion polymer. The resulting polymers are useful as binders in ambient cure surface coating application.
