PURPOSE:To provide the titled compsn. having a strength suitable for practical use and excellent electrical conductivity and resistance to heat and chemicals, consisting of a polyester resin, graphite and carbon black. CONSTITUTION:The titled compsn. is obtd. by blending 30-98.5pts.wt. polyester resin having an intrinsic viscosity of 0.3 or above and contg. at least 80mol% of ethylene terephthalate repeating units, 1-50pts.wt. graphite having an average particle size of 0.01-500mu such as scaly graphite and 0.5-20pts.wt. carbon black having an average particle size of 1-400mmu. If necessary, not more than 60wt% inorg. filler having a particle size of 20mu or below, such as talc, and/or not more than 50wt% reinforcing fiber having a diameter of 15mu or below, such as glass fiber, may be blended with said compsn. EFFECT:Moldings having a volume resistivity of 1X10<1>-1X10<9>OMEGA.cm can be obtd.
