Abstract: The present application relates to a process for producing an aqueous polymer dispersion of polymerized ethylenically unsaturated monomers M by a multistage aqueous radical emulsion polymerization comprising a first aqueous radical emulsion polymerization step of a first monomer composition M.a and subsequently a further aqueous radical emulsion polymerization step of a second monomer composition M.b. The present application also relates to aqueous polymer dispersions obtainable by such a process and to the use thereof, in particular as a binder in coating compositions. The process comprises a multistage aqueous radical emulsion polymerization of ethylenically unsaturated monomers M, comprising a) at least one non-ionic, monoethylenically unsaturated monomer M1 having a solubility in deionized water of at most 60 g/L at 25° C.

Abstract: A description is given of an aqueous polymer dispersion comprising a polymer which is obtainable by emulsion polymerization from a monomer mixture comprising as hydrophilic monomers ethoxylated (meth)acrylate monomer, acid monomer, and C1 to C20 hydroxyalkyl(meth)acrylate; and also at least one hydrophobic principal monomer, selected from C1 to C20 alkyl(meth)acrylates and vinylaromatics; and also, optionally, further monomers. This polymer is preparable by at least two-stage emulsion polymerization, where in a first polymerization stage the predominant fraction or the entire amount of the hydrophilic monomers is used, and in a later polymerization stage the predominant fraction or the entire amount of the hydrophobic monomers is used. The polymer dispersion is a suitable binder for aqueous particle dispersions, more particularly of sound deadener compositions, which comprise inorganic and optionally also organic particulate solids.
