A process for the preparation of electrically conductive polymers which have conductivities greater than 10-2 S/cm and possess improved stability to oxygen, comprising treating an organic unsaturated polymer of the series of the polyphenylenes, heterophenylenes and polyacetylenes, in the absence of moisture and of oxygen, first with an organic nitroso compound and then with a conventional dopant, the latter being, in particular H2SO4, AsF5, SbF5, UF6, SbCl5, AlCl3, BF3, CF3SO3H, VOCl3, HClO4, NO+SbF6-, NO2+SbF6-, NO+AsF6, NO+PF6-, I2, Br2, ICl, PF5, CrO2Cl2, NO2+PF6-, NO+BF4-, NO+ClO4-, (CF3)2SO4, NbF5, TaF5, WF6, FeCl3, CdCl2, 2,4,6-trinitrophenol, 2,4,6-trinitrophenylsulfonic acid or 2,4,6-trinitrophenylcarboxylic acid or lithium, sodium, potassium, calcium, barium, radium or an amide of these metals. |
