(JA) 積層体
Abstract
(EN)
To provide a laminated tube having excellent interlayer adhesion and durability thereof, while maintaining various properties, such as low-temperature impact resistance, burst pressure strength, and flexibility. [Solution] This laminated tube has at least two layers that are adjacent to each other, wherein an aliphatic polyamide composition that constitutes one layer includes: an aliphatic polyamide in which the ratio of the number of methylene groups to the number of amide groups is a specified value or more; and an elastomeric polymer which may contain a copolymerized polyamide having a specific unit, and a constitutional unit derived from an unsaturated compound having a carboxyl group and/or an acid anhydride group.

L'invention aborde le problème de la réalisation d'un tube stratifié ayant une excellente adhérence intercouche et une excellente durabilité de celle-ci, tout en conservant diverses propriétés telles que la résistance au choc à basse température, la résistance à la pression de rupture et la flexibilité. La solution selon l'invention porte sur un tube stratifié qui comprend au moins deux couches qui sont adjacentes l'une à l'autre. Une composition de polyamide aliphatique, qui constitue une couche, comprend : un polyamide aliphatique dans lequel le rapport du nombre de groupes méthylène au nombre de groupes amides est égal ou supérieur à une valeur spécifiée ; et un polymère élastomère qui peut contenir un polyamide copolymérisé ayant une unité spécifique, et une unité constitutive dérivée d'un composé insaturé ayant un groupe carboxyle et/ou un groupe anhydride d'acide.
