| 简介 |
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 - NH 2 ‰¤ 80 0.32 ‰¤ P < 6.46 0.50 ‰¤ M < 17.00 2 ‰¤ M / P ‰¤ 3 wherein [COOH] represents a concentration (µeq/g) of a terminal carboxyl group in the polyamide (X); [NH 2 ] 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. |
