PURPOSE:A polyamide resin composition having improved electrical conductivity and good properties, comprising a polyamide, finely divided carbon or metal, or a fibrous conductive material, and a plasticizer. CONSTITUTION:A composition prepared by incorporating (A) 5-40 wt.% of finely divided carbon or a metal or fibrous conductive material with (B) 3-30 wt.%, preferably 5-20 wt.%, of a plasticizer compatible with the polyamide and (C) 0-30 wt.%, preferably 20 wt.% or less, of a synthetic rubber homogeneously. The size of the conductive finely divided powder is 20 mu or less, preferably 5 mu or less, and the fibrous material preferably has a diameter of 1-20 mu. Benzenesulfonamide, N-butyl-p-toluenesulfonamide, pentadecylphenol, etc. may be cited as the plasticizer. |
