Abstract
A resin composition exhibiting excellent antistaticity and static charge dissipating performance and having extremely small variations of antistatic properties (saturated static voltage and half-life period of static voltage) on the surface of a molded article and a transportation jig for electronic field made of the above resin composition are provided by using a resin composition produced by compounding (A) 100 parts by weight of a thermoplastic resin with (B) 1 to 30 parts by weight of a carbon fiber having a diameter of 1 nm to 1 &mgr;m, a length of 1 &mgr;m to 3 mm and a volume resistivity of smaller than 1 &OHgr;cm and (C) 5 to 200 parts by weight of an antistatic polymer having a surface resistivity of 10 to 10 &OHgr; (measured under impressed voltage of 500V), a melting point of 100° C. or above, an apparent melt viscosity of 10 to 1,000 Pa·s at apparent shear rate of 1,000 sec at 260° C. and an apparent melt viscosity ratio of the antistatic polymer to the thermoplastic resin of 0.01 to 1.3 under the above condition.
