1. A copolymer of an aniline monomer of the general formula:
- ##STR4## where R is in the ortho- or meta- position and is selected from the group consisting of hydrogen, C1-18 alkyl, C1-6 alkoxy, amino, chloro, bromo, sulpho, carboxy, hydroxy and the group ##STR5## where R" is selected from the group consisting of alkyl and aryl; and
R'"'"' is selected from the group consisting of hydrogen, C1-6 alkyl and aryl;
with at least one other aniline monomer of formula I as defined above, the copolymer including counterions X where X is selected from the group consisting of C1-, Br-, SO4=, BF4=, PF6=, H2 PO3-, H2 PO4-, arylsulphonate, arenedicarboxylate, arenecarboxylate, polystyrene sulphonate, polyacrylate, alkylsulphonate, vinylsulphonate, vinylbenzene sulphonate, cellulose sulphonate, cellulose sulphate and a perfluorinated polyanion.
