ELECTROCONDUCTIVE RESIN COMPOSITION

摘要

A resin material with excellent conductivity is disclosed which is preferabl y used for fuel cell separators. Specifically, disclosed is a conductive resin composition having a volume resistivity of not more than 5 .times. 10-2 .OMEGA..cndot.cm. The conductive resin composition is obtained by blending 1 00 parts by weight of a liquid crystalline polymer (A) with 200-500 parts by weight of at least one graphite (B) selected from artificial graphite which contains not less than 95 weight% of fixed carbon and has an average particl e diameter of 50-200 .mu.m, flake graphite and amorphous graphite, and melt- mixing the blend under such a condition that the ratio of the extrusion amou nt per unit time "Q" (kg) to the number of screw revolutions "N" (rpm) "Q/N" during mixing is within the range of 0.1-1.5.
