Abstract: The present invention describes a method for the manufacturing of a multi-stage polymer by the following steps: a) polymerizing monomer mixture (A) comprising a-i) vinyl acetate and a-ii) at least one vinyl ester of an aromatic carboxylic acid via free radical emulsion polymerization to obtain copolymer (A); and b) polymerizing monomer mixture (B) comprising b-i) vinyl acetate and b-ii) at least one vinyl ester of aliphatic branched or unbranched carboxylic acids having at least 3 carbon atoms, via free radical emulsion polymerization in the presence of copolymer (A) to obtain the multi-stage polymer with the proviso that said monomer mixture (B) can also be polymerized first to obtain a copolymer (B) and subsequently monomer mixture (A) is polymerized in the presence copolymer (B) to obtain the multi-stage polymer.

Abstract: Disclosed are improved carpet products made using certain types of coating compositions to secure carpet fibers to a carpet backing or substrates and/or to secure one or more carpet scrims or other layers to carpet backing. The coating compositions, which can be in the form of either precoating or skip coating compositions, are made from latex binder emulsions based on interpolymers emulsion polymerized from vinyl esters, ethylene, and a multifunctional cross-linking co-monomer such as an unsaturated silane. Such emulsions are also stabilized with surfactant emulsifiers but are substantially free of protective colloid stabilizers. The multifunctional co-monomer alters interpolymer molecular weight, branching and/or flow properties such that films formed from such interpolymers exhibit relatively low elongation values. When the emulsion binder exhibits such non-elongating film-forming characteristics, the carpet coating composition made from such binders can be easily processed without build-up on carpet processing apparatus. Such binder emulsions which are stabilized substantially only with surfactant emulsifiers, and not with protective colloids, also have excellent compatibility with other coating composition components.
