LAMINATE
SOLUTION: A laminate is obtained by laminating an X layer and a Y layer, wherein the X layer is a 4-methyl-1-pentene-based resin composition which contains 10-90 pts.mass of a 4-methyl-1-pentene-based polymer (A) having a melting point (TmA) measured by DSC of 200°C or higher, 1-50 pts.mass of polya...

Zusammenfassung: | SOLUTION: A laminate is obtained by laminating an X layer and a Y layer, wherein the X layer is a 4-methyl-1-pentene-based resin composition which contains 10-90 pts.mass of a 4-methyl-1-pentene-based polymer (A) having a melting point (TmA) measured by DSC of 200°C or higher, 1-50 pts.mass of polyamide (B), 0.1-20 pts.mass of a modified 4-methyl-1-pentene-based polymer (C), and 1-40 pts.mass of a 4-methyl-1-pentene-based polymer (D) having a melting point that is not measured by DSC or a melting point (TmD) measured by DSC of lower than 200°C (total amount of components (A), (B), (C) and (D) is 100 pts.mass).EFFECT: The laminate has heat resistance and gas permeability of a 4-methyl-1-pentene-based polymer, and is excellent in mechanical strength such as elongation at break and delamination strength.SELECTED DRAWING: None
【解決手段】X層と、Y層とが積層されてなる積層体であって、X層が、DSCで測定した融点(TmA)が200℃以上である4-メチル-1-ペンテン系重合体(A)10~90質量部と、ポリアミド(B)1~50質量部と、変性4-メチル-1-ペンテン系重合体(C)0.1~20質量部と、DSCで融点が計測されないか、またはDSCで測定した融点(TmD)が200℃未満である4-メチル-1-ペンテン系重合体(D)1~40質量部とを含む、4-メチル-1-ペンテン系樹脂組成物(ただし成分(A)、(B)、(C)および(D)の合計量を100質量部とする)から構成される積層体。【効果】本発明の積層体は、4-メチル-1-ペンテン系重合体が持つ耐熱性、ガス透過性を保ち、さらに破断伸びなどの機械強度に優れ、層間剥離強度にも優れる。【選択図】なし |
