The invention relates to the use of a polymer dispersion for producing anti-drumming compounds, said polymer dispersion containing at least one polymer which can be obtained by emulsion polymerization of radically polymerisable monomers and the polymer has an average molecular weight of more than 100,000, preferably more than 100,000 to 350,000. The invention also relates to corresponding anti-drumming compounds which contain the polymer dispersion and to a method for damping vibrations or oscillations of components in vehicles. 本发明涉及聚合物分散体用于制备隔音组合物的用途，所述聚合物分散体含有至少种可通过可自由基聚合的单体的乳液聚合获得的聚合物，且所述聚合物的平均分子量大于100 000，优选大于100 000至350 000。本发明还涉及含有所述聚合物分散体的相应隔音组合物，还涉及种用于减弱车辆部件的振动或振荡的方法。
