Abstract: The invention relates to the use of aqueous multi-stage polymerizate dispersions, which can be obtained by radically initiated aqueous emulsion polymerization, having a soft phase and a hard phase and a stage ratio of hard to soft of 25 to 95 wt% to 75 to 5 wt%, wherein the glass transition temperature (Tg) of the soft phase as the first stage is -30 to 0 °C and the glass transition temperature of the hard phase as the second stage is 20 to 60 °C, containing at least one monomer of general formula (I) in which the variables have the following meaning: n = 0 to 2, R1, R2, R3 = hydrogen or a methyl group independently of each other, X = O or NH, Y = H, alkali metal, NH

Abstract: The present invention relates to an aqueous polymer dispersion whose dispersed addition polymer P comprises, copolymerized in free-radically polymerized form, at least one polar monomer having a water solubility of greater than 50 g/liter (measured at 20° C.), and obtainable by free-radically initiated aqueous emulsion polymerization, the polar monomer being metered to the reaction mixture during the polymerization process at a variable, i.e., nonconstant rate, for example in the sense of a rate gradient. The present invention further relates to processes for preparing these aqueous polymer dispersions, to their use as binders and/or in coatings, and also to coatings comprising the polymer dispersion of the invention.
