VIBRATION DAMPER COMPOSITION |
| 摘要 |
<p>A vibration damper composition which has a ratio of (G'0C</ G'>40<C?) of 15 or less, wherein G'>0<C? and G'>40<C? represent values of storage modulus (G') at 0?C and at 40?C as obtained by the measurement of dynamic viscoelasticity in a shear mode, and exhibits a loss tangent (tan d) obtained in the above measurement of 0.4 or more at 0?C to 40?C; and a vibration damper and a pressure sensitive adhesive double coated tape having damping property which use the composition. Preferably, the vibration damper composition comprises a di-block copolymer (A') comprising a polymer block having a monomer unit derived from an aromatic vinyl compound and having a number average molecular weight of 10,000 or less and a polymer block having a monomer unit derived from iso-butylene. The composition exhibits high damping property and also reduced temperature dependency for rigidity around room temperature, and further can be subjected to hot melt application.</p> |
