Abstract: The invention relates to a polymer dispersion containing i) polymer particles which consist of units of ethylenically unsaturated monomers and are dispersed in an aqueous medium; ii) a water-soluble polymer polyelectrolyte which on a polymer skeleton carries a plurality of ionic groups having the same charging properties or groups which can be ionized such that they form such groups; and iii) an ionic tenside which carries an ionic group having the opposite charging properties of the polymer polyelectrolyte or a group which can be ionized such that it forms such a group. The polymer dispersion can be coagulated by simple dilution with water.

Abstract: A description is given of a polymer dispersion comprising i) polymer particles dispersed in an aqueous medium and composed of units of ethylenically unsaturated monomers, ii) a water-soluble polymeric polyelectrolyte which along a polymeric backbone carries a large number of ionic groups of uniform charge character or groups which can be ionized to such groups, and iii) an ionic surfactant which carries an ionic group having a charge character opposite to that of the polymeric polyelectrolyte, or a group which can be ionized to such a group. The polymer dispersion can be coagulated by simple dilution with water.
