A process for the preparation of a polyaniline salt which comprises polymerizing an aromatic amine in the presence of a protonic acid, an ionic surfactant, a radical initiator and a mixture of aqueous and hydrocarbon solvents, and separating the polyaniline salt in solution form from the reaction mixture.
A process for the preparation of a polyaniline salt which comprises polymerizing an aromatic amine in the presence of a protonic acid, ionic surfactant, a radical initiator and a mixture of aqueous and hydrocarbon solvents, separating the polyaniline salt in solution form from the reaction mixture, adding a non-solvent to the polyaniline salt solution to precipitate the polyaniline salt from solution, and separating the precipitated polyaniline salt from the reaction mixture.
