PROBLEM TO BE SOLVED: To obtain a compsn. which is excellent in moldability and gives a molded item excellent in hinging properties, flame retardance, and mechanical properties by compounding a polyamide resin comprising specified amts. of a polyamide 66 resin and a polyamide 6 resin with specified amts. of a triazine- based flame retardant and a metal salt of an aliph. carboxylic acid having the number of carbon atoms specified. SOLUTION: 100 pts.wt. polyamide resin comprising 90-50 wt.% polyamide 66 resin pref. having a relative viscosity (according to JIS K6810 in 98% sulfuric acid in a concn. of 1% at 25 deg.C) of 2.2-3.5 and 10-50 wt.% polyamide 6 resin pref. having a relative viscosity (measured under the same conditions as above) of 2.0-4.5, pref. 2.2-3.5, is compounded with 2-20 pts.wt. triazine-based flame retardant (e.g. melamine cyanurate) and 0.005-1 pt.wt. metal salt of a 22-30C aliph. carboxylic acid (e.g. sodium montanate). |
