Abstract
An electroconductive polymer doped with tetracyanoethylene anion radicals was obtained by chemical oxidation of undoped polypyrrole. Its electronic absorption spectra were investigated. Broadening of the line of the EPR spectrum was observed when the anion radical was introduced into the polymer; this may be due to slow spin-spin exchange between the radical and the polar chain of the polymer.
