Abstract: Radiation and peroxide-curable oligomeric emulsions are prepared by mixing water, an .alpha.,.beta.-ethylenically unsaturated oligomer (e.g. an unsaturated polyester), a reactive, nonionic surfactant containing allyl unsaturation, and a metallic salt drier under high shear agitation until a stable emulsion is formed. Coatings prepared from these emulsions are tack and mar free and demonstrate good resistance to organic solvents and water.

Abstract: Water-in-oil emulsions of monomers which form water-soluble polymers are polymerized in the presence of a biphase initiator system containing both an oil-soluble initiator and a water-soluble initiator or activator or alternatively a water-soluble initiator and an oil-soluble activator which results in polymers having improved performance characteristics. In addition, the system permits the satisfactory polymerization of monomers which could not have been reproducibly polymerized.
