    Abstract: Described is an adhesive composition in the form of an aqueous polymer dispersion comprising tackifiers, a compound crosslinking via keto or aldehyde groups and a pressure-sensitive adhesive polymer which is formed by emulsion polymerization from soft (meth)acrylic ester monomers, acid monomers, monomers having keto or aldehyde groups, styrene and optionally further monomers, wherein the polymerization may be carried out in the presence of chain transfer agents. The pressure-sensitive adhesive polymer has certain gel contents. The pressure-sensitive adhesive composition may be used to produce adhesive labels, adhesive tapes or adhesive films.

    Abstract: A description is given of the use of a polymer dispersion for producing sound deadener compositions, the polymer dispersion comprising at least one polymer obtainable by emulsion polymerization of radically polymerizable monomers, and the polymer having a weight-average molecular weight of more than 100 000, preferably of more than 100 000 to 350 000. A description is also given of corresponding sound deadener compositions which comprise the polymer dispersion, and of a method for damping oscillations or vibrations of vehicle components.

    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. Also described is a method for damping oscillations or vibrations of vehicle components.
