POLYAMIDE RESIN COMPOSITION

摘要

The present invention relates to a polyamide resin composition comprising polyamide (X) comprising a diamine unit containing 70 mol % or more of a metaxylylenediamine unit and a dicarboxylic acid unit and an alkali compound (A), wherein the following equations (1) to (4) are satisfied:;10≦([COOH]—[NH2])≦80  (1);0.32≦P<6.46  (2);0.50≦M<17.00  (3);2≦M/P≦3  (4);wherein [COOH] represents a concentration (μeq/g) of a terminal carboxyl group in the polyamide (X); [NH2] represents a concentration (μeq/g) of a terminal amino group in the polyamide (X); P represents a mole concentration (μmol/g) of a phosphorus atom contained per g of the polyamide resin composition; and M represents a sum (μmol/g) of values obtained by multiplying a mole concentration of an alkali metal atom and a mole concentration of an alkaline earth metal atom each contained per g of the polyamide resin composition by valencies thereof respectively.
