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.
