Title (EN) LAYERED TUBE
(FR) TUBE MULTICOUCHE
(JA) 積層チューブ
Abstract:
(EN) Provided is a layered tube comprising a layer including a specific aliphatic polyamide composition and a layer including a semi-aromatic polyamide composition containing a semi-aromatic polyamide having a specific structure or a mixture thereof, said layers being disposed adjacent to each other, wherein the aliphatic polyamide composition includes: an aliphatic polyamide having a melting point no more than a specific value and having a ratio of the number of methylene groups to the number of amide groups that is at least a specific value; an aliphatic polyamide having an absolute difference in the solubility parameter/SP value with the aforementioned aliphatic polyamide, such absolute difference falling within a specific range; and an elastomer polymer containing a constituent unit derived from an unsaturated compound having a carboxyl group and/or an acid anhydride group.
(FR) L'invention concerne un tube multicouche comprenant une couche qui comporte une composition de polyamide aliphatique spécifique et une couche qui comporte une composition de polyamide semi-aromatique et contient un polyamide semi-aromatique présentant une structure spécifique ou un mélange de ceux-ci, lesdites couches étant disposées adjacentes l'une à l'autre. La composition de polyamide aliphatique comprend : un polyamide aliphatique présentant un point de fusion inférieur ou égal à une valeur spécifique et présentant un rapport du nombre de groupes méthylène sur le nombre de groupes amides qui est au moins une valeur spécifique ; un polyamide aliphatique présentant une différence absolue de la valeur de paramètre de solubilité/SP avec le polyamide aliphatique susmentionné, laquelle différence absolue est située dans une plage spécifique ; et un polymère élastomère contenant une unité constitutive dérivée d'un composé insaturé comportant un groupe carboxyle et/ou un groupe anhydride d'acide.
(JA) 特定の脂肪族ポリアミド組成物を含む層と特定の構造を有する半芳香族ポリアミド又はその混合物を含有する半芳香族ポリアミド組成物を含む層を有し、該両層が隣接する積層チューブにおいて、脂肪族ポリアミド組成物が、融点が特定の値以下であって、かつメチレン基数のアミド基数に対する比が特定の値以上の脂肪族ポリアミドと同脂肪族ポリアミドとの溶解性パラメーターSP値の差の絶対値が特定範囲にある脂肪族ポリアミド、並びにカルボキシル基及び/又は酸無水物基を有する不飽和化合物から誘導される構成単位を含有するエラストマー重合体を含む積層チューブが提供される。
