Abstract
A description is given of the use of a polymer dispersion for preparing sound deadener compositions, the polymer dispersion being obtainable by emulsion polymerization of free-radically polymerizable monomers in the presence of at least one protective colloid which is an amphiphilic graft copolymer. Preferred protective colloids have a polyalkylene oxide main chain and vinyl ester-comprising side chains. 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.
