Provided is a curable composition for damping materials excellent in heat resistance, oil resistance and damping property, as well as a damping material obtained therefrom. Specially provided is a curable composition for damping materials, containing a vinyl-based polymer (I) having more than one crosslinkable functional groups on average and having at least one of the crosslinkable functional groups at the terminus thereof, and a vinyl-based polymer (II) having one or less crosslinkable functional group on average, wherein the content of the vinyl-based polymer (II) is 50 to 95 parts by weight based on 100 parts by weight of the vinyl-based polymers (I) and (II), as well as a damping material obtained by curing the curable composition.
本发明提供了一种用于阻尼材料的可固化组合物,该组合物具有优异的耐热性、耐油性和阻尼性能,还提供了由此获得的阻尼材料。特别提供了一种用于阻尼材料的可固化组合物,该组合物含有平均具有一个以上可交联官能团并在其末端具有至少一个可交联官能团的乙烯基聚合物(I),以及平均具有一个或更少可交联官能团的乙烯基聚合物(II),其中乙烯基聚合物(II)的含量为 50 至 95 重量份(以 100 重量份的乙烯基聚合物(I)和(II)为基准),以及通过固化该可固化组合物获得的阻尼材料。
