A carpet back coating composition which is an aqueous emulsion polymerization product of ethylene, vinyl acetate, and a ethylenically unsaturated hydroxy-functional monomer to form an emulsion copolymer which is combined with a crosslinking agent selected from the group consisting of multifunctional aziridine, multifunctional isocyanate, and multifunctional epoxide. Carpets prepared with the carpet back coating compositions exhibit improved wet strength. The improvement in wet strength is achieved by means of crosslinking reactions which do not generate volatile organic compounds as by-products.

Crosslinkable carpet-back coating with hydroxy-functionalized vinyl acetate emulsion polymers

The invention is directed to carpet coating compositions which utilize an emulsion binder which is prepared by emulsion polymerization of ethylene, a vinyl ester monomer having a Tg of between about 20.degree. C. and about 45.degree. C., and an essentially non-reactive monomer having a Tg of less than 10.degree. C., and to carpet products prepared with the carpet coating compositions.

Carpet coating compositions

Carpet coating compositions are disclosed which comprise 40 to 80 percent by weight filler and 20 to 60 percent by weight of a latex binder, the binder comprising an emulsion polymer of

Emulsion binder for carpet and carpet tiles

Flocking adhesives are prepared from an aqueous emulsion prepared by the emulsion polymerization of a vinyl ester of an alkanoic acid interpolymerized with:
