Abstract:
A functionalized copolymer in the form of its aqueous dispersion or water-redispersible powder, said copolymer being the polymerized product of monomers consisting essentially of:a) one or more monomers selected from the group consisting of vinyl esters of unbranched or branched alkylcarboxylic acids 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 selected from the group consisting of ethylenically unsaturated, hydrolyzable silicon compounds, epoxysilanes, aminosilanes, and mercaptosilanes, c) from 0.05 to 5.0% by weight of one or more monomers selected from the group consisting of ethylenically unsaturated epoxide compounds, d) from 0 to 2.0% by weight of one or more monomers selected from the group consisting of ethylenically unsaturated 1,3-dicarbonyl compounds, all percents being % by weight based on the overall weight of the monomers a) used.
