Description

【請求項3】 熱可塑性エラストマーがポリウレタンまたはポリスチレン系エラストマーである請求項2に記載の積層体。
3. A laminate of a thermoplastic elastomer is described inMotomeko 2 is polyurethane or polystyrene-based elastomer.

特に本発明においては、ポリオレフィン系エラストマーとして、下記(i)〜(iii)を満たすエチレン−α−オレフィン共重合体用いることがより好ましい。
(i)密度が0.90g/cm以上であること、(ii)α−オレフィン含有量が8〜25モル%であること、(iii)MFRが5〜200g/10分であること。密度が0.90g/cm未満であったり、α−オレフィン含有量が25%を超えたりすると、ポリマー自体の膠着性が大きく、シート化した後の取り扱いが困難となる場合がある。一方、α−オレフィンの含有率が8モル%未満であると、融点が高くなり、熱融着性が低下するため、他素材との複合が困難となる場合がある。シート状物とした際の取扱い性や接着性などの点から、α−オレフィン含有率は、9〜20モル%がより好ましい。また、熱接着の観点から考慮すると該重合体の融点は50〜150℃が好ましく、さらに好ましくは、80〜140℃である。なお融点は、示差走査熱量計(DSC)を用いて測定し、吸熱ピークのトップピークを読み取ることで求めることができる。

In particular, in the present invention, it is more preferable to use an ethylene-α-olefin copolymer satisfying the following (i) to (iii) as the polyolefin elastomer.
(I) the density is 0.90 g / cm 3 or more, (ii) the α-olefin content is 8 to 25 mol%, and (iii) the MFR is 5 to 200 g / 10 min. Or a density of less than 0.90 g / cm 3, alpha-olefin content If it or exceed 25%, a large sticking of the polymer itself, there is a case where handling after a sheet becomes difficult. On the other hand, when the content of the α-olefin is less than 8 mol%, the melting point is increased and the heat-fusibility is reduced, so that it may be difficult to combine with other materials. From the viewpoint of the handling property and adhesion property as a sheet material, the α- olefin content, and more preferably 9 to 20 mol%. From the viewpoint of heat bonding, the melting point of the polymer is preferably from 50 to 150 ° C, more preferably from 80 to 140 ° C. The melting point can be determined by measuring with a differential scanning calorimeter (DSC) and reading the top endothermic peak.
