Abstract
Abstract A poly(hetero-arylene vinylene) containing, as its major constituent unit, a repeating unit represented by the general formula <IMAGE> (wherein X is a sulfur or oxygen atom), which is obtained by subjecting a sulfonium salt represented by the general formula <IMAGE> (wherein X has the same definition as given above, R1 and R2 are independently a hydrocarbon group of 1 to 10 carbon atoms, and A- is a counter ion) to condensation polymerization using an alkali to obtain a precursor polymer, and subjecting the precursor polymer to stretching and orientation and then to a treatment for sulfonium salt elimination or subjecting the precursor polymer in one step to stretching and orientation and to a treatment for sulfonium salt elimination, as well as a highly conductive composition thereof.
