Abstract
Water-redispersible polymer powder compositions are obtained by means of free-radical-initiated polymerization in aqueous medium of one or more monomers of vinyl esters of unbranched or branched alkylcarboxylic acids having from 1 to 15 carbon atoms, methacrylic esters and acrylic esters of alcohols having from 1 to 15 carbon atoms, vinylaromatics, olefins, dienes and vinyl halides and subsequent drying of the polymer dispersion, wherein one or more silanes of the general formula (RO)RSiRX (1) where X is an amino- or epoxy-containing radical are added before drying of the polymer dispersion. The powders are especially useful in tile adhesives for tiles having low water absorbtion capacity.
