<p>PROBLEM TO BE SOLVED: To provide a polyamide resin composition that is tightly adherable to a fluorine resin and does not cause or rarely causes defects such as overreaction at the adherence interface when a multilayer composite material of a fluororesin and a polyamide resin is manufactured. SOLUTION: This polyamide resin composition comprises (A) a polyamide wherein the mole ratio of the carboxyl end group to the amino end group is >1, (B) an aromatic diamine, and (C) a base with a pKa (25 deg.C) of >=10 or a salt thereof. The relative viscosity of the polyamide (A) (in 0.5 wt.% m-cresol solution at 25 deg.C) is, for example, on the order of 1.9-2.7. A cyclic amine or a salt thereof can be used as the base or a salt thereof (C).</p> |
