Fused metal phthalocyanine polymers with higher molecular weight were prepared by baking equal molar quantities of pyromellitic dianhydride and phthalic anhydride with urea, ammonium chloride, ammonium molybdate and various metal sulfates. The structure of the polymers were investigated by comparison with their corresponding metal phthalocyanine derivatives. The elemental, I.C.P., spectra, electrical measurements and X-ray diffraction pattern were made to characterize the polymers. The conductivities of the polymers are in the range of 10(-4)-10(-6) S cm-1.
