  • Highly electroconductive pyrolyzed product retaining its original shape and composition formed therefrom
    Patent number: 4599193
    Abstract: A highly electroconductive carbonaceous material is obtained by pyrolysis in an inert atmospherea conjugated polymer represented by the general formula--R--CH.dbd.CH).sub.nwherein R is an aromatic hydrocarbon group which forms a consecutive carbon to carbon conjugated system with the vinylene group, and n is an integer of at least 2, at a temperature above 400.degree. C., or an aromatic polyimide at a temperature of 2000.degree. C. or above. Further, a highly electroconductive composition is obtained by treating the carbonaceous material mentioned above with a dopant.
