Modified polyvinyl alcohols containing polymer compositions

The invention relates to modified polyvinyl polymer-containing compositions in the form of their aqueous dispersions and water-redispersible powders based on homopolymers or copolymers of one or more monomers from the group comprising Vinylester of unbranched or branched alkylcarboxylic acids having 1 to 15 carbon atoms, methacrylic acid ester and acrylate of alcohols having 1 to 15 C atoms, vinylaromatics, olefins, dienes and vinyl halides, characterized in that as modified polyvinyl alcohols, those having a latent carboxylic acid function and / or such are included with phosphorus-containing comonomer units.
