ｙｎｅ／ｃＪの範囲であることが、制振性能と形状保持
性との兼ね合いから好ましい。In the damping material composition of the present invention, the dynamic elastic modulus E' is lxl07 to 5x10''d in the range of 0 to 60°C.
The range of yne/cJ is preferable from the viewpoint of a balance between vibration damping performance and shape retention.

Since it falls within this range, it is suitable as a vibration damping material composition.
非晶質ポリオレフィン樹脂の数平均分子量は１、０００

Must be in the range ~20,000.
数平均分子量が１、０００未満であると、常温でも柔ら
かくなり過ぎるので凝集力が弱くなる。If the number average molecular weight is less than 1,000, it becomes too soft even at room temperature, resulting in weak cohesive force.
このため、硬質基材との接着が不良になりやすいという

生じたりするので、好ましくない。Furthermore, when the number average molecular weight exceeds 20,000, the non-quality polyolefin resin becomes rubbery and has a high melt viscosity. For this reason, the amorphous polyolefin resin has a thickness of 0.
5 It becomes difficult to process the sheet in advance into a thin sheet of about fi1 or to cast it onto a hard substrate using a doctor knife or the like. The degree of crystallinity of the non-quality polyolefin resin is preferably 20% or less, more preferably 10% or less.

《分布している。When the loss coefficient η of the damping laminate is measured under the conditions of this example while changing the measurement temperature, η≧0. The temperature range No. 1 is the temperature range in which the damping performance of the vibration damping laminate is good. In the damping layer bodies of Examples 1 to 5, this temperature range is also widely distributed around room temperature, from 27 to 60°C to 0°C to 60°C.
このことから、本発明の制振性積層体は、特に室温付近
で優れた制振性能を持つことが判る。This shows that the vibration damping laminate of the present invention has excellent vibration damping performance especially near room temperature.

。従って、各種の制振材や遮音材に用いるのに好適であ
る。The damping material composition of the present invention has an amorphous polyolefin resin having a specific molecular weight or a composition thereof as a main component. Therefore, it has excellent vibration damping performance and shape retention near room temperature. Therefore, it is suitable for use in various vibration damping materials and sound insulation materials.
又、この制振材組成物は溶融粘度が低い。従って、加熱
溶融して硬質基村上に流延したり、シート状に成形した
りすることが容易である。Moreover, this damping material composition has a low melt viscosity. Therefore, it is easy to heat and melt it and cast it onto a hard substrate, or to form it into a sheet.
又、この制振材組成物は非晶質の樹脂なので、制振性積
層体材の製造の際、制振材が肉痩したり、金属板との接
着が不良となったりすることがない。In addition, since this damping material composition is an amorphous resin, the damping material will not become thin or have poor adhesion to the metal plate when producing the damping laminate material. .
