An improved synthetic route to polypyrrole salt was accomplished using methanesulfonic acid as a novel dopant along with potassium persulfate as the oxidant employing inverted emulsion polymerization technique. Polypyrrole salt was obtained in high-weight percent yield (83.77%) with respect to the amount of monomer used and the reaction time was drastically reduced (1 h 10 min.) as compared to the previously reported synthesis methods. Characterization of the salt yielded satisfactory results. Inverted emulsion polymerization technique has several unique and distinct advantages over conventional techniques which facilitate the synthesis of fused five membered heterocyclic rings which are otherwise difficult to synthesize, and hence sparsely reported in the literature.
