Aniline-phenylenediamine copolymers

The electrical conductivity of materials based on polyaniline can be contro lled on submolecular level by the copolymerization of aniline with various phenylenediamines. The joint chemical oxidation of aniline with phenylenedi amines yields products with the de conductivity spanning over more than ele ven orders of magnitude. The dependence of the conductivity on the composit ion of reaction mixture was investigated for all three comonomers, o-, m-, and p-phenylenediamine. The electrical properties of copolymers and mixture s of corresponding homopolymers are compared.
