    摘要： A material for vibration-absorbable mounts, which comprises a cured product of a composition comprising (A) an acrylic polymer having at least one alkenyl group capable of undergoing hydrosilylation reaction, (B) a hydrosilyl group-containing compound and (C) a hydrosilylation catalyst as essential components, has a distinguished vibration-absorbing characteristic such as a loss tangent (tan δ) of 0.5 or more, and also a distinguished heat resistance, and thus is sufficiently suitable for vibration-absorbable mounts for HDDs as mounted on automobiles. Furthermore, the material for vibration-absorbable mounts has distinguished heat resistance, oil resistance, vibration-absorbing characteristic, compression set characteristic, low hardness, cleanliness (out gassing property and non-corrosiveness), etc. and thus can be effectively used as vibration-absorbable mounts for electric and electronic parts provided with opto-magnetic drives, for example CD, DVD, HDD, etc. for automobiles, and also as vibration-absorbable pads, etc. for electric and electronic part units.
