The polyamide resin composition
2011
Disclosed is a polyamide resin compositionwhich contains an alkali compound (A) and a polyamide (X) comprising a dicarboxylic acid unit and a diamine unit containing at least 70 mol% of an m-xylylene diamine unitwherein the following formulae (1 to 4) are satisfied: (1) 10 = ([COOH] - [NH2]) = 80; (2) 0.32 = P < 6.46; (3) 0.50 = M < 17.00; and (4) 2 = M/P = 3. (In the formulae: [COOH] represents the concentration ([mu]eq/g) of non-terminal carboxyl groups in the polyamide (X); [NH2] represents the concentration ([mu]eq/g) of non-terminal amino groups in the polyamide (X); P represents the mole concentration ([mu]mol/g) of phosphorus atoms contained per 1g of polyamide resin composition; and M represents the sum ([mu]mol/g) of the mole concentration of alkali metal atoms and the mole concentration of alkaline earth metal atoms contained per 1g of polyamide resin composition each multiplied by the valency thereof.
