The present disclosure provides embodiments of aqueous compositions comprising a dispersed polymer for preparing a carpet backing, methods for producing a carpet product, and methods for preparing a polymer-backed carpet. The aqueous composition can be prepared by polymerizing monomers including at least 50 percent by weight of at least one compound selected from the group consisting of alkyl acrylates and alkyl methacrylates having at least 4 carbon atoms in the alkyl. at least 30 percent by weight of at least one compound selected from the group consisting of styrene and alkyl acrylates and alkyl methacrylates having not more than 3 carbon atoms in the alkyl, less than 3 percent by weight of a hydroxyalkyl acrylate, and a copolymerizable acid in an amount up to 5 percent by weight.
La présente invention concerne des modes de réalisation de compositions aqueuses qui comprennent un polymère dispersé pour la préparation dun dossier de tapis, des procédés de fabrication dun produit de tapis et des procédés de préparation dun tapis à endos polymère. La composition aqueuse peut être préparée par polymérisation de monomères qui comprennent au moins 50 pourcent en poids dau moins un composé choisi dans le groupe constitué d'acrylates dalkyle et de méthacrylates dalkyle contenant au moins 4 atomes de carbone dans lalkyle; au moins 30 pourcent en poids dau moins un composé choisi dans le groupe constitué de styrène et d'acrylates dalkyle et de méthacrylates dalkyle contenant 3 atomes de carbone ou moins dans lalkyle; moins de 3 pourcent en poids dun acrylate dhydroxyalkyle; et un acide copolymérisable en une quantité pouvant atteindre 5 pourcent en poids.
