Damping material with a high molecular emulsion polymer

The present invention relates to the use of polymer dispersions for the production of damping material, wherein the polymer dispersion contains at least one polymer obtained by emulsion polymerization of radically polymerizable monomers, and wherein polymer 100000 greater, preferably has a weight average molecular weight of 100,000 ultra ～350000. The present invention also provides damping material corresponding containing the polymer dispersion, and a method of attenuating the vibration or oscillation of the vehicle components.
