Abstract
(EN)
Disclosed is a polyamide composite resin having excellent bas barrier properties as well as sufficiently excellent flexibility and durability which is capable of forming a good gas-barrier layer for refrigerant transport hoses without having a multilayer structure. Also disclosed is a refrigerant transport hose which is easily produced using such a polyamide composite resin. Specifically disclosed is a polyamide composite resin containing a polyamide and a polyolefin, wherein the polyamide includes a metaxylenediamine as a constitutional unit. The polyamide composite resin, which is a polymer alloy wherein a polyolefin is added as a flexibility-imparting agent, is excellent in bas barrier properties, flexibility and durability. A refrigerant transport hose has the innermost layer composed of such a polyamide composite resin.

Est décrite une résine composite polyamide ayant d’excellentes propriétés barrière bas ainsi qu'une flexibilité et une durabilité assez excellentes susceptible de former une bonne couche barrière bas pour des tuyaux de transport réfrigérants sans avoir une structure multicouche. Est également décrit un tuyau de transport réfrigérant qui est facilement fabriqué en utilisant une résine composite polyamide. Est particulièrement décrite une résine composite polyamide contenant une polyamide et une polyoléfine, dans laquelle la polyamide inclut une métaxylènediamine en tant qu’unité constitutionnelle. La résine composite polyamide, qui est un alliage polymère dans lequel est ajoutée une polyoléfine en tant qu’agent conférant de la flexibilité, est excellente de par ses propriétés de barrière bas, sa flexibilité et sa durabilité. Un tuyau de transport réfrigérant a sa couche la plus intérieure composée d’une telle résine composite polyamide.
