ABSTRACT:
A thermoplastic resin composition comprising 100 parts by mass of a polyamide resin composition (A) and 0.1 to 10 parts by mass of a carbodiimide compound (B) having two or more carbodiimide groups. The polyamide resin composition (A) contains a polyamide resin (a-1) and nylon 11 and/or nylon 12 (a-2) in an amount of 5 to 95% by mass of the component (a-1) and 95 to 5% by mass of the component (a-2) each based on a total amount of the components (a-1) and (a-2). The polyamide resin (a-1) is constituted by diamine units 70 mol % or more of which are derived from m-xylylenediamine and dicarboxylic acid units 70 mol % or more of which are derived from a C4to C20α,ω-linear aliphatic dicarboxylic acid. The thermoplastic resin composition is excellent in barrier property, strength and impact resistance, in particular, barrier property to alcohol-containing fuels, and suitably used as various shaped articles such as fuel containers, tubes and parts.
