ABSTRACT:
An aqueous latex is disclosed which possesses improved water resistance at reduced acrylic ester content for use in exterior latex paints. This latex comprises an aqueous emulsion copolymer of monomers consisting essentially of from 10% to 30% of vinylidene chloride together with 20% to about 50% of styrene, and from 40% to 60% of monoethylenic ester, preferably acrylic or methacrylic esters, the mixture of monomers providing the copolymer with a glass transition temperature in the range of -10.degree. C. to +10.degree. C., and from 0% to 10.0% of a monomer promoting adhesion, the proportions being based on the total weight of monomers copolymerized.
