Abstract

The present invention provides a process for producing carbon dichalcogen polymers having a conductivity of about 10.sup.-8 S/cm without doping treatment which is increased to 10.sup.-4 to 10.sup.-2 S/cm by doping, by polymerizing carbon dichalcogenide monomers (carbon disulfide, carbon diselenide, etc.) in the form of a solution thereof under a low pressure in the presence of an anionic catalyst.
