Summary:Described is a sound-insulating composition comprising a polymer dispersion comprising at least one dispersed (meth) acrylic polymer obtainable by emulsion polymerization of radically polymerizable (meth) acrylic monomers, a high-density filler mixture and a specific dispersing aid, wherein the sound-insulating composition, upon drying, has volume shrinkage or only a very low volume expansion. 描述了包含聚合物分散体的隔声组合物，所述聚合物分散体包含至少一种可通过可自由基聚合的(甲基)丙烯酸单体的乳液聚合获得的分散的(甲基)丙烯酸聚合物、高密度填料混合物和特定的分散助剂，其中所述隔声组合物在干燥后有体积收缩或仅有非常低的体积膨胀。
