POLYAMIDE RESIN FOR FUEL BARRIER AND MULTILAYER MOLDED PRODUCT CONSISTING OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a barrier material excellent in fuel barrier property, heat resistance and moldability/processability. SOLUTION: The polyamide resin for a fuel barrier is obtained by polycondensation of a diamine component containing≥70 mol% of m-xylylene diamine and a dicarboxylic acid component containing≥60 mol% of a mixed dicarboxylic acid in which the molar ratio of a 4-20Cα,ω-linear aliphatic dicarboxylic acid and naphthalene dicarboxylic acid is 30:70-95:5. The multilayer molded product is obtained by utilizing the polyamide resin. COPYRIGHT: (C)2006,JPO&NCIPI
