    Abstract: 1,155,275. Styrene/acrylate and/or methacrylate copolymers. BADISCHE ANILIN- & SODA FABRIK A.G. 28 Oct., 1966 [29 Oct., 1965], No. 48419/66. Heading C3P. Polymer dispersions are produced by copolymerizing styrene with 5-95% of esters of acrylic and/or methacrylic acid with C 1-8 alcohols in an aqueous medium in the presence of catalysts and emulsifiers, 0À01-2% of a protective colloid being gradually added after 20-80/) of the monomers have been copolymerized, and then completing the copolymerization. The esters may be ethyl, n- or tert-butyl, 2-ethylhexyl or cyclohexyl acrylate and/or methyl or butyl methacrylate. The copolymer may also include acrylic acid, acrylamide, methacrylamide, methyl vinyl carbinol, or vinyl sulphonic acid. Polyvinyl methyl ether may be present during the polymerization. The protective colloid may be a polyvinyl alcohol, which may be acetalized with n-butyraldehyde and completely hydrolysed, a hydroxyethyl cellulose, an ammoniacal solution of polyacrylic acid or a copolymer of acrylic acid/acrylamide/ acrylonitrile/methyl acrylate. The emulsifier may be the sodium salt of the sulphonated nonyl-phenol/ethylene oxide, ethylene oxide/noctylphenol, sodium vinyl sulphonate or propylene oxide/ethylene oxide. The catalyst may be potassium persulphate.

    Abstract: 1,148,060. Aqueous dispersions of vinyl ester polymers. BADISCHE ANILIN- & SODA-FABRIK A.G. 5 Aug., 1966 [6 Aug., 1965], No. 35105/66. Heading C3P Aqueous dispersions of vinyl ester polymers are formed by polymerizing the monomer(s) in aq. phase in the presence of an emulsifier comprising (A) 15-70% of at least one copolymer of 50-90% of acrylic and/or methacrylic acid with at least one other nonionic ethylenically unsaturated monomer and which is soluble in water at a pH of at least 4, (B) 15-70% of at least one polyalkylene oxide or its derivative which is not sulphonated and (C) 15-70% of at least one sulphonated long chain alcohol having at least 8 carbon atoms. The vinyl ester polymer may be derived from vinyl propionate and acrylic acid or sodium vinyl sulphonate, tert-butyl acrylate and methyl vinyl carbinol or vinyl acetate acrylic acid or n-butyl acrylate. The emulsifier may acomprise (A) a copolymer of acrylic acid, acrylamide, methyl acrylate and/or acrylonitrile, (B) an adduct of ethylene oxide and sperm oil alcohol or iso-octylphenol and (C) a sulphonation product of (B). The polymerization may be in the presence of vinylpyrrolidone potassium persulphate, formic acid, ascorbic acid, n-dodecyl mercaptan. The aq. dispersion may be compounded with methyl cellulose, sodium metahexaphosphate, ammonium polyacrylate, aq. ammonia, chalk, rutile, kaolin, talc, dolomite, zinc white, titanium dioxide, china clay, blanc fixe, satin white and/or casein.

    Abstract: 1,129,974. Coating. BADISCHE ANILIN - & SODA-FABRIK A.G. 4 Feb., 1966 [5 Feb., 1965], No. 4948/66. Heading B2E [Also in Division C3] Substrates may be coated with aqueous dispersions of vinyl ester polymers prepared by polymerising vinyl esters in the presence of catalysts and modified polyvinyl alcohols which are saponification products of copolymers of 90 to 99.9 weight per cent of a vinyl ester of a C 1-3 aliphatic saturated monocarboxylic acid and 0.1 to 10 weight per cent of a vinyl ester of a C 4-20 aliphatic saturated monocarboxylic acid in which the carboxylic group is α to a tertiary or quarternary carbon atom. In an example cardboard is coated with a dispersion of polyvinyl propionate prepared in the presence of a saponified vinyl acetate/vinyl 2,2,4,4- tetramethyl valerate copolymer, said dispersion being mixed with a paste of lithopone in aqueous ammonium polyacrylate solution.
