Patent ID: 8062557

Claim:
A thermoplastic resin composition for producing automobile exterior parts, comprising the following components (A) to (H) in the following weight percentage ranges based on 100% by weight of the sum of the entire components constituting said composition: 18 to 80% by weight of component (A) which is a polyamide 6 resin having a viscosity number, as measured in accordance with ISO-307, of 80 to 120 ml/g and a ratio of a content of terminal carboxyl groups (unit: μeq/g) to a content of terminal amino groups (unit: μeq/g) of 2≦(terminal carboxyl group content/terminal amino group content)≦6; 5 to 25% by weight of component (B) which is a hydrogenated product of a block copolymer comprising a vinyl aromatic compound polymer block and a conjugated diene compound polymer block; 3 to 15% by weight of component (C) which is a graft-modified hydrogenated product of a block copolymer comprising a vinyl aromatic compound polymer block and a conjugated diene compound polymer block, said hydrogenated product being graft-modified with maleic anhydride in an amount of 2.6 to 5.0% by weight based on 100% by weight of said graft-modified hydrogenated product; 1 to 5% by weight of component (D) which is conductive carbon black having a BET specific surface area of not less than 600 m 2 /g and a DBP oil absorption of not less than 300 ml/100 g; 10 to 30% by weight of component (E) which is talc having an average particle diameter of 0.5 to 10 μm; 0.1 to 2% by weight component (F) which is a phosphonite compound; 0.5 to 5% by weight of component (G) which is an ethylene-vinyl alcohol resin; and 0 to 1% by weight of component (H) which is a pentaerythritol based phosphite.
