ABSTRACT:
There is disclosed a process for preparing vinyl dispersion resins by conducting the polymerization reaction of the vinyl monomer or monomers in an aqueous alkaline medium, using an oil-soluble polymerization initiator, at low temperatures, in the presence of an emulsifier and, optionally, at least one long straight chain alcohol containing from 14 to 24 carbon atoms, and in the presence of an electrolyte, such as for example, ammonium carbonate ((NH.sub.4).sub.2 CO.sub.3), and wherein the reaction ingredients are thoroughly mixed, or homogenized, prior to polymerization. The aqueous emulsion of the polymer(s) so produced are capable of being dried into friable aggregates of individual spheres of polymer particles. The dried resin can easily be formulated into plastisols of high North Fineness and high gloss. In addition, polymer buildup in the reactor is reduced.
