Abstract: Aq. copolymer dispersions, suitable for pigment-free coating of papers, e.g. hot-sealing-, decorative- and packaging papers, are prepd. by polymerising 45-60 wt.% styrene, 25-59 wt. % of an acrylate and/or methacrylate of an 8-12 C non-tert. alkanol, 0.5-5 wt. % N-methylolacryl-and/or methacrylamide and/or N-alkyoxymethylacryl- and/or -methacrylamide, 1-3 wt. % acrylic- and/or methacrylic acid, and opt. 10 wt. % further olefinically unsatd. monomers, in an aq. emulsion, using standard polymsn. catalysts, emulsifiers and temps. Papers treated are less sensitive to humid atmos., e.g. tropical conditions, than papers coated with dispersions of styrene copolymers contg. only lower alkyl acrylates or methacrylates, do not draw together or corrugate, and show an tendency to yellowing.

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.
