    摘要： 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.

    摘要： Described is a polymer dispersion comprising in an aqueous medium (a) dispersed particles of a polymer containing more than from 5 to 20% by weight of &agr;,&bgr;-ethylenically unsaturated mono- or dicarboxylic acid, (b) a dissolved polymer containing from 60 to 100% by weight of &agr;,&bgr;-ethylenically unsaturated mono- or dicarboxylic acid, and (c) an alkoxylated long-chain amine. Heat-curable compositions are obtained by adding polyfunctional alcohols and, optionally, reaction accelerant. The polymer dispersions and the heat-curable compositions are suitable for use as binders for textile sheetlike structures and for moldings.
