Abstract: Polyamic acid with carbazole and copper-phthalocyanine was synthesized by con-densation polymerization. Heat resistant polyimide was obtained by thermal treatment of the polyamic acid. It was found that the initial degradation temperature of the polylmide was more than530℃ and it was confirmed by IRanalysis that the polyamic acid was completely converted to polyimide after the heat treatment process. The photoconductivity of the P/Rsystem has been improved by the incorporation of phthalocyanine group into the polyimide main chain.

Key words: Carbazole, Copper-phthalocyanine, Polyimide
