Title (EN) LAYERED TUBE
(FR) TUBE MULTICOUCHE
(JA) 積層チューブ
Abstract:
(EN) Provided is a layered tube comprising a layer containing a specific aliphatic polyamide composition and a layer containing an ethylene/vinyl acetate copolymer saponified substance, said layers being disposed adjacent to each other, wherein: the absolute difference in the solubility parameter/SP value, between 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 and another polyamide in the aliphatic polyamide composition falls within a specific range; and the aliphatic polyamide composition includes an aliphatic polyamide 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 contenant une composition de polyamide aliphatique spécifique et une couche contenant une substance saponifiée de copolymère d'éthylène/acétate de vinyle, lesdites couches étant disposées adjacentes l'une à l'autre, la différence absolue dans la valeur de paramètre de solubilité/SP, entre un polyamide aliphatique ayant un point de fusion inférieur ou égal à une valeur spécifique et ayant un rapport du nombre de groupes méthylène au nombre de groupes amide qui est supérieur ou égal à une valeur spécifique et un autre polyamide dans la composition de polyamide aliphatique se situant dans une plage spécifique ; et la composition de polyamide aliphatique comprenant un polyamide aliphatique et un polymère élastomère contenant une unité constitutive dérivée d'un composé insaturé ayant un groupe carboxyle et/ou un groupe anhydride acide.
(JA) 特定の脂肪族ポリアミド組成物を含む層とエチレン/酢酸ビニル共重合体ケン化物を含む層を有し、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、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それ以外の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り、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。
