Substituted polyanilines are of interest due to their increased solubility over polyaniline. However, early experiments showed that the substituted materials, while exhibiting a higher solubility (and thus workability), were also less conducting. Here, it is shown that dialkoxy substitution of aniline increases solubility of the polymer while not reducing the conductivity. The lower steric hindrance caused by teh methoxy groups in comparison with methyl groups is thought to be responsible.
