Resin composition and molded article containing the same

Abstract

The present invention provides a polyamide resin composition not only having an appropriate melt viscosity despite addition of a conductive filler thereto but also having excellent moldability, conductivity, low-temperature impact resistance, and fuel barrier properties. The present invention is a polyamide resin composition containing specific amounts of a polyamide, a modified resin, and a conductive filler. The polyamide contains: dicarboxylic acid units containing 50 mol % or more of terephthalic acid units and/or naphthalenedicarboxylic acid units; and diamine units containing 60 mol % or more of aliphatic diamine units having 4 to 18 carbon atoms, and has terminal amino groups in an amount of 5 to 60 μmol/g. The modified resin has been modified with an unsaturated compound having a carboxyl group and/or an acid anhydride group. In the polyamide resin composition, a difference between the number of moles (MI) of the terminal amino groups of the polyamide and the number of moles (MII) of the carboxyl groups and the acid anhydride groups of the modified resin in 1 g in total of the polyamide and the modified resin is −5.0 μmol or more and less than 4.0 μmol, and the number of moles (MII) is more than 4.0 μmol.
