  • Patent number: 6863985
    Abstract: Functionalized copolymers hydrophobicized with silicones, in the form of aqueous dispersions or water-redispersible powders are prepared by copolymerizing a) from 60 to 99.89% by weight of one or more monomers selected from the group consisting of vinyl esters of optionally branched C1-15 alkylcarboxylic acids, methacrylates and acrylates of C1-15 alcohols, vinylaromatics, olefins, dienes, and vinyl halides, b) from 0.01 to 30% by weight of one or more silicones with from 10 to 1,000 SiO(CnH2n+1)2 repeat units where n is from 1 to 6, and where from 90 to 100% by weight of the silicones b) contain at least one but not more than two polymerizable groups, 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 epoxysilanes, aminosilanes and mercaptosilanes, and d) from 0.05 to 5.

  • Patent number: 6624243
    Abstract: The invention provides functionalized copolymers in the form of their aqueous dispersions or water-redispersible powders, based on a) one or more monomers from the group consisting of vinyl esters of unbranched or branched alkylcarboxylic acids having 1 to 15 carbon atoms, methacrylic esters and acrylic esters of alcohols having 1 to 15 carbon atoms, vinyl aromatics, olefins, dienes, and vinyl halides, b) from 0.05 to 5.0% by weight of one or more hydrolyzable silane monomers from the group consisting of ethylenically unsaturated, hydrolyzable silicon compounds and hydrolyzable silicon compounds from the group consisting of epoxysilanes, aminosilanes, and mercaptosilanes, c) from 0.05 to 5.0% by weight of one or more monomers from the group consisting of ethylenically unsaturated epoxide compounds, d) from 0 to 2.
