PROBLEM TO BE SOLVED: To provide a high molecular weight, thermoplastic polyurethane composition characteristically resistant to aliphatic hydrocarbon fuels.SOLUTION: There is provided a high molecular weight, thermoplastic polyurethane composition characteristically resistant to aliphatic hydrocarbon fuels, where the polyurethane composition is adapted for use as an aliphatic hydrocarbon fuel barrier in the construction of flexible fuel containers and the polyurethane is the reaction product of a poly(diethylene adipate) glycol reacted with a non-hindered diisocyanate and an aliphatic chain extender. 【課題】脂肪族炭化水素燃料に特徴的に耐性のある高分子量熱可塑性ポリウレタン組成物を提供すること。【解決手段】脂肪族炭化水素燃料に特徴的に耐性のある高分子量熱可塑性ポリウレタン組成物（ここで上記ポリウレタン組成物は、可撓性燃料容器の構造における脂肪族炭化水素燃料バリアとして使用するために適合され、上記ポリウレタンは、非ヒンダードジイソシアネートおよび脂肪族鎖伸長剤と反応したポリ（ジエチレンアジペート）グリコールの反応生成物である）。【選択図】なし
