  • Patent number: 10457827
    Abstract: The invention relates to an aqueous vinyl acetate-ethylene-copolymer dispersion for carpet coating compositions, which is obtained by means of radical-initiated emulsion polymerization, in an aqueous medium, of vinyl acetate and ethylene and optionally additional ethylenically unsaturated comonomers, characterized in that, for stabilization of the dispersion, 5 to 10 wt %, based on the total weight of the comonomers, of one or a plurality of partially saponified and low-molecular polyvinyl alcohols having a hydrolysis degree of 80 to 95 mol % and a Höppler viscosity, in 4% aqueous solution, of 1 to 5 mPas (method according to Höppler at 20° C., DIN 53015) are contained.
    Type: Grant

    Inventors: Holger Künstle, Timo Melchin, Robert Tangelder
  • Patent number: 10227726
    Abstract: The use of redispersible polymer powders containing no organic emulsifier for a binder in the production of carpeting is surprisingly superior to use of the same polymers in the form of an aqueous dispersion. Tuft removal force in particular, is improved. The compositions contain no thickener, or a reduced level of thickener.

  • Patent number: 7649067
    Abstract: The present invention relates to a vinyl ester based polymer latex composition obtainable by free radical emulsion polymerization in substantial absence of a protective colloid and in the presence of no or small amounts of a surfactant, and to a process of making the same. The invention further pertains to a dispersion incorporating said vinyl ester based polymer latex composition, products comprising said dispersion, and various uses of the dispersion.

  • Patent number: 6746555
    Abstract: The invention provides low-emission adhesives based on an aqueous, protective-colloid-free polymer dispersion or water-redispersible dispersion powders, obtainable therefrom, of vinyl acetate-ethylene copolymers, obtainable by free-radically initiated emulsion polymerization, in aqueous medium and in the presence of one or more emulsifiers, of a comonomer mixture comprising a) from 5 to 50% by weight of ethylene, b) from 20 to 80% by weight of at least one vinyl ester from the group of vinyl esters of unbranched or branched carboxylic acids having 1 to 9 carbon atoms whose homopolymers have a glass transition temperature Tg >0° C., c) from 5 to 70% by weight of at least one vinyl ester from the group of vinyl esters of branched carboxylic acids having 8 to 13 carbon atoms whose homopolymers have a glass transition temperature Tg <0° C., d) from 0.
