    摘要: 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 subsequent 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 sound deadener compositions, which comprise inorganic and optionally also organic particulate solids. Also described is a method for damping vibrations or oscillations of vehicle components.
