Poly(m‐phenylene disulfide) treated with SbF5 gives an unstable blue‐black material. Heating of doped samples at 155°C leads to some stabilization to ambient conditions; doped and heated pellets exhibit a conductivity of 10−9 and 10−5 S/cm for vapor and liquid doping, respectively. To investigate backbone modifications, polymer powders have been treated with large amounts of liquid SbF5 and an analysis of the IR spectra of the extracted samples has been tried in comparison with that of pristine polymer. Evidence for SbF ion has been found in the IR spectra of the complexes.
