Abstract
Acrylic latices containing epoxy resins are prepared by emulsion polymerization in which an epoxy resin (polyepoxide) is incorporated into at least one of the monoethylenic monomers, including an epoxy-reactive monomer, and the monomers including the epoxy resin are emulsified into water containing surfactant to provide the oil phase of an oil-in-water emulsion. The monomers are then polymerized in the aqueous emulsion using a free radical polymerization catalyst and a reaction temperature which does not cause premature reaction between the epoxy groups and the reactive monomer. This provides thermosetting latex particles of fine particle size in the presence of less emulsifying agent than is normally needed.
