Abstract
The invention relates to a polymer dispersion for paper coating compositions obtainable by means of a radically initiated, aqueous emulsion polymerization of a) 60 to 97% by weight of vinyl acetate, b) 2 to 30% by weight of ethylene, c) 0.5 to 5% by weight of at least one ethylenically unsaturated silane monomer, d) 0.5 to 5% by weight of at least one ethylenically unsaturated carboxylic acid, based in each case on the total weight of the monomers used for the polymerization, and the data in % by weight summing in each case to 100% by weight, in the presence of one or more polymeric emulsifiers.
