Abstract
1,253,999. Aqueous polymer latices. REVERTEX Ltd. 22 Sept., 1969 [30 Sept., 1968], No. 46367/68. Headings C3G and C3P. An aqueous film-forming latex is prepared by subjecting a pre-formed latex prepared by aqueous emulsion copolymerization of (a) one or more vinyl esters of saturated unbranched aliphatic monocarboxylic acids, which acids contain 2 to 4 carbon atoms with (b) one or more vinyl esters of branched saturated aliphatic monocarboxylic acids of which the carboxyl groups are attached to tertiary and/or quaternary carbon atoms and which acids contain not less than 9 carbon atoms to at least one further polymerization step by mixing the pre-formed latex with an ethylenically unsaturated monomer or mixture of ethylenically unsaturated monomers, the monomer or monomers being different from the monomer precursors of the pre-formed latex, and subsequently causing the monomer or monomers to polymerize, the or at least one of the admixed monomers being so chosen that if polymerized in the absence of the pre-formed latex but in the presence of any other admixed monomer it yields a homopolymer or copolymer having a glass transition temperature higher than that of polyvinyl acetate. In the examples, a latex is prepared by copolymerizing vinyl acetate and, the vinyl ester of a branched monocarboxylic acid in the presence of sodium dioctyl sulphosuccinate, hydroxyethyl cellulose, sodium bicarbonate, crotonic acid, water, carbon tetrachloride, ammonium persulphate and polyethoxylated nonylphenol. Then styrene, methyl methacrylate and butyl acrylate are polymerized in the presence of the latex and tert-butyl hydroperoxides, an aqueous solution of sodium formaldehyde sulphoxylate and an aqueous solution of ascorbic acid. Compositions are prepared from the pre-formed latex and the products of the further polymerization containing titanium dioxide, tetrasodium pyrophosphate, an ethylene oxide-propylene oxide block copolymer, ammonia solution, sodium salt of a copolymer of maleic anhydride and an a-olefin, hydrocarbon oil defoaming agent, solution of polyacrylic thickener, water, butoxy-ethanol and propylene glycol.
