    Abstract: Vinyl acetate/ethylene copolymer powders are obtained by spray-drying of the corresponding aqueous polymer dispersions while simultaneously adding finely divided inorganic materials as anti-caking agents. The polymer powders thus obtained have an excellent storage stability, are easily dispersible in water and yield plastics mortars of high water resistance and plasterings made therefrom which are free from cracks.

    Abstract: Bisstyryl-substituted aryl compounds of the formula (I): (I) where X is arylene and R1 and R5 are substituents common to the dye art. The compounds are useful as optical brighteners, particularly for acrylonitrile polymers, and give excellent whitening having good fastness properties.

    Abstract: 1357281 Ethylene-vinyl acetate copolymer coating compositions FARBWERKE HOECHST AG 15 Feb 1972 [16 Feb 1971] 6945/72 Headings C3G and C3P Aqueous coating compositions comprise (1) a mineral pigment, (2) a pigment dispersing substance, (3) a binder comprising an aqueous dispersion of a copolymer of ethylene, vinyl acetate and optionally one or more other monomers, and (4) 2 to 20 weight per cent based on the solids content of the copolymer dispersion of a graft polymer of a vinyl ester or vinyl ester and an unsaturated carboxylic acid on a polyalkylene oxide. The binder may also comprise conventional water-soluble binders such as casein, starch and polyvinyl alcohol. The pigment may be china clay, calcium carbonate, barium sulphate, titanium dioxide or satin white. The pigment dispersing agent may be a polyacrylic acid salt or polyphosphate. Examples describe the preparation of paper coating compositions comprising china clay; sodium salt of polyacrylic acid; -ethylene/vinyl acetate, ethylene/vinyl chloride/vinyl acetate or ethylene/vinyl pivalate/vinyl acetate copolymer dispersion; starch, casein or polyvinyl alcohol; and graft polymers of vinyl acetate or vinyl acetate and acrylic acid on polyethylene glycols.

    Abstract: Aqueous dispersions of copolymers consisting of 50-99.9% by weight of a vinyl ester of a saturated monocarboxylic acid having from 1 - 18 carbon atoms, 0.1 - 15% by weight of an alpha -haloalkane carboxylic acid vinyl ester of the formula wherein R1 is hydrogen, a halogen atom or an alkyl radical having 1 - 16 carbon atoms, R2 is hydrogen, a halogen atom or an alkyl radical having 1 - 13 carbon atom and X is a halogen atom, and 0 - 49.9% by weight of at least one other ethylenically unsaturated monomer which can be cross-linked while drying with 0.05% to 10% by weight calculated on the total mixture of an aminoplast resin, a polyamine, a polyamidoamine or a mixture of Formaldehyd and ammonia or an amine. The mixture of the dispersion and the cross-linking agent is stable, and cross-linking will start only when the mixture is applied to a substrate such as a fiber.
