ABSTRACT:
The fuel-barrier polyamide resin of the present invention is a product of the polycondensation of a diamine component comprising 70 mol % or higher of m-xylylenediamine and a dicarboxylic acid component comprising 70 mol % or higher of a mixed dicarboxylic acid which comprises a C4to C20α,ω-linear aliphatic dicarboxylic acid and at least one dicarboxylic acid selected from the group consisting of isophthalic acid and naphthalenedicarboxylic acid in a molar ratio of 30:70 to 95:5. The polyamide resin is excellent in not only fuel-barrier property and heat resistance, but also moldability and recyclability, and therefore suitably used as a barrier material of fuel containers.
