    摘要： The invention provides a process for preparing adhesives having improved adhesion, in the form of their aqueous dispersions or water-redispersible dispersion powders, by emulsion polymerization in the presence of polyvinyl alcohol with or without drying of the dispersion obtainable by this process, which comprises polymerizing a comonomer mixture comprising a) one or more monomers from the group consisting of the vinyl esters of unbranched and branched carboxylic acids of 1 to 10 carbon atoms, the esters of acrylic acid and methacrylic acid with branched and unbranched alcohols of 1 to 12 carbon atoms, vinylaromatic compounds, vinyl halides and alpha-olefins, and b) from 0.01 to 50% by weight, based on the overall weight of the comonomers, of a vinyl ester of alpha-branched tertiary monocarboxylic acids of 11 carbon atoms, in the presence of c) from 0.1 to 15% by weight, based on the overall weight of the comonomers, of polyvinyl alcohol.
