Abstract
A description is given of a nonaqueous sound deadener composition comprising (a) a nonpulverulent polyacrylate binder having a K value in the range from 10 to 35, measured as a 1% strength solution in tetrahydrofuran; (b) inorganic fillers; and a radically polymerizable compound which has at least one radically polymerizable C—C double bond and possesses a boiling point at atmospheric pressure of greater than 160° C. Also described is a method for damping oscillations or vibrations of components of vehicles and machines, using the sound deadener composition of the invention.
