✦ Synopsis

Polymeric copper phthalocyanine containing peripheral carboxyl groups has been converted into the corresponding polyimides by condensing the anhydride of the latter with 4,4'-diaminodiphenyl ether. The resulting polyimides have been converted into an environmentally stable electrically conductive material by thermal means. The electrical conductivity of the heated polymer could be controlled by the duration of thermal treatment; there is a range of electrical conduction behaviour from an insulator to a semiconductor and tending to the metallic region.
