ABSTRACT OF THE DISCLOSURE PROCESS FOR PRODUCING STABLE LARGE PARTICLE SIZE LATICES This invention relates to the preparation of stable large particle size latices for use in water reducible coatings. It specifically discloses an improved stable large particle size latex that is useful in the manufacture of water reducible coatings, comprising: (a) a resin which is comprised of, based on 100 weight percent of monomeric units within the resin: (1) from about 50 to about 90 percent of at least one monomer selected from the group consisting of styrene, .alpha.-methyl styrene and vinyl toluene, (2) from about 10 to about 40 percent of at least one alkyl acrylate monomer wherein the alkyl moiety contains from 3 to 5 carbon atoms; and (3) from about 1 to about 10 percent of at least one unsaturated carbonyl compound selected from the group consisting of acrylic acid, methacrylic acid fumaric acid, itaconic acid, maleic acid and maleic anhydride; (b) water; (e) at least one phosphate-ester surfactant and (d) as a secondary surfactant between about 0.01 and about 2 phr (parts per 100 parts of rubber) of at least one polyol which has a molecular weight between about 2,000 and about 20,000 which has the structural formula: Image wherein n and m are integers, and wherein n is greater than m, and wherein ? indicates that the distribution of monomeric units can be random.
