Abstract:
1. A functionalized copolymer which has been hydrophobicized with silicones and is in the form of an aqueous dispersion or water-redispersible powder, comprising the polymerized product of a) from 60 to 98.89% by weight of one or more monomers selected from the group consisting of vinyl esters of optionally branched C b) from 0.01 to 30% by weight of one or more silicones with from 10 to 1,000 (C c) from 0.05 to 5.0% by weight of one or more hydrolyzable silane monomers selected from the group consisting of ethylenically unsaturated hydrolyzable silicon compounds, and hydrolyzable silicon compounds selected from the group consisting of epoxysilanes, aminosilanes and mercaptosilanes, d) from 0.05 to 5.0% by weight of one or more monomers selected from the group consisting of ethylenically unsaturated epoxy compounds, wherein said %'s by weight are based on the total weight of the monomers and total 100%, wherein the copolymer comprises a vinyl acetate-ethylene copolymer or a copolymer of vinyl acetate and ethylene and at least one vinyl ester of an α-branched carboxylic acid having 9 or 10 carbon atoms, each of these copolymers optionally further comprising one or more auxiliary monomers.
