There is disclosed a polyamide resin composition comprising (A) 100 parts by weight of a polyamide (a) composed mainly of a xylylenediamine component and an .alpha.,.omega.-straight chain asphaltic dibasic acid component, or a combination of the polyamide (a) and polyamide 66, (B) 1 to 15 parts by weight of polyamide 12, (C) 0.01 to 5 parts by weight (in terms of copper) of a copper compound, (D) 1 to 15 parts by weight of carbon black, and (E) an alkali metal halide of such an amount that the number of halogen atoms of the alkali metal halide is 0.3 to 4 per one copper atom of the above copper compound. Said polyamide resin composition has an excellent weather resistance, moldability, and mechanical properties, and can be injection-molded.

Polyamide resin composition

A polyamide molding composition is disclosed comprising the admixture of glass fibers, nylon 6,6, and an MX nylon, obtained from the condensation of a xylylenediamine and an .alpha.,.omega.-straight chain aliphatic dibasic acid having 6-12 carbon atoms.

Polyamide resin molding composition

A glass fiber-reinforced polyamide resin molding material, comprising a polyamide resin obtained by the condensation reaction of xylylene diamine with at least one member selected from straight-chain aliphatic .alpha.,.omega.-dicarboxylic acids having 6 to 12 carbon atoms and incorporated therein, glass fiber in an amount of 5 to 50% by weight based on the total weight of the polyamide resin and the glass fiber, and a shaped article obtained by molding aforesaid molding material.
