The invention relates to a process for the preparation of an aqueous polymer dispersion for releasable pressure-sensitive adhesive films by means of radically initiated, aqueous emulsion polymerization of one or more ethylenically unsaturated monomers from the group comprising esters of acrylic acid and methacrylic acid with unbranched or branched alcohols having 1 to 12 carbon atoms, Vinyl esters of unbranched or branched carboxylic acids having 1 to 12 carbon atoms, vinyl aromatics, vinyl halides, olefins and dienes, characterized in that 0.01 to 2.0% by weight of polar, ionic or nonionic comonomers or mixtures thereof are copolymerized, where in the copolymerization of polar, ionic comonomers, alone or in a mixture, the proportion of which is at most 1.0% by weight, and the data in% by weight are based in each case on the total weight of the comonomers. |
