Two new classes of highly unsaturated polymers—polyethynylpolyarenes and polyazopolyarenes are synthesized by oxidative polycondensation of polyethynylarenes in the first case and of aromatic diamines in the second one and investigated. The polymers have common formulas H[(CC)kAr(CC)k]nH and H2NArN(NArN)NArNH2 respectively. The polymers either keep the conjugation along the main chain or the conjugation is intentionally broken. This is attained by changing the structure of the arylenic part of the monomers. Depending on the structure, electrical properties of the polymers vary in a wide range. For example the conductivity at 20°C. varies from 10−2 to 10−20 ω−1 cm.−1. The temperature dependence of conductivity is σ = σ0 exp {−E/kT}. The activation energy is specially predetermined by the structure and can vary in the range of 0.1 to 4.7 e.v. Similarly magnetic, dielectric, catalytic and other properties and solubility can be changed by varying the structure.
