  • Patent number: 9951243
    Abstract: Disclosed are aqueous carpet-coating compositions suitable for use as binders or adhesives in carpet products. Such compositions, prior to being applied to carpet substrates and cured, comprise: A) a selected type of vinyl acetate/ethylene (VAE) copolymer dispersion which has been stabilized with emulsifiers and a cellulose ether-based protective colloid, and B) at least one carbon black based filler in the form of a dispersion/slurry with a solids content between 20 and 70%. These coating compositions exhibit especially desirable initial viscosity and viscosity stability characteristics. Carpet products which utilize such coating compositions to provide binder and/or adhesive layer within the carpet are also disclosed. Such carpet products can have desirable odor-controlling and odor-absorbing properties.

  • Publication number: 20170081544
    Abstract: An aqueous carpet coating composition comprises: (A) at least one particulate filler material; and (B) a stabilized copolymer dispersion comprising: (a) a copolymer formed by emulsion polymerization of a monomer mixture comprising a vinyl ester of an alkanoic acid having 1 to 18 carbon atoms and 1 to 25 pphm of ethylene, wherein the copolymer comprises particles having a weight average particle size, dw, of at least 200 nm as determined by Beckman Coulter LS 13320; (b) water; and (c) a stabilizing system comprising (i) 1 to 4 pphm of an emulsifier component consisting of at least one non-ionic surfactant and (ii) 0.5 to 4 pphm of at least one first polyvinyl alcohol component having a degree of hydrolysis greater than 92 mol %.

  • Publication number: 20170029544
    Abstract: The present invention relates to a process for the emulsion polymerization of free-radically polymerizable, ethylenically unsaturated main monomers, and optionally further auxiliary monomers copolymerizable therewith, wherein the polymerization comprises a polymerization reaction phase starting with the first addition of an initiator or starting with the first addition of monomers, whatever is later, and ending with the completion of the addition of the initiator or the completion of the addition of total monomers, whatever is later, wherein the reaction temperature is increased during said polymerization reaction phase from a start temperature in the range of about 30° C. to about 85° C. to an end temperature in the range of about 60° C. to about 160° C., and wherein the polymerization temperature is increased for at least 25% of the duration of said polymerization reaction phase.

  • Publication number: 20080044565
    Abstract: Process for applying a polyvinyl ester dispersion-based adhesive by means of nozzle application and use of polyvinyl ester dispersion-based adhesives A description is given of an application process for polyvinyl ester dispersion-based adhesives through nozzles to a substrate, wherein an aqueous, primarily emulsifier-stabilized vinyl ester polymer dispersion having a solids content of at least 40% by weight, a viscosity of less than 8000 mPas, and a vinyl ester polymer glass transition temperature of ?30 to +40° C. is supplied to the nozzle and is applied from the nozzle, in the form of a thin jet or of a predeterminedly interrupted thin jet, to the substrate. The process can be implemented for long periods without interruption, and the adhesive bonding takes place at high speed.

  • Publication number: 20080039572
    Abstract: A description is given of an aqueous vinyl ester copolymer dispersion stabilized with a combination of at least one protective colloid and of at least one emulsifier, said dispersion having a viscosity of less than 8000 mPa*s, a weight average dw of the particle sizes of 0.5 to 10 ?m, and a ratio of weight average to number average of the particle sizes, dw/dn, of at least 2.5, and the polymer possessing a glass transition temperature of between ?30 and +15° C. The dispersion can be used as an adhesive for nozzle application processes.
