Abstract

Described is a process for preparing polyaniline polymer which includes contacting aniline monomers with (a) hydrogen peroxide, (b) at least one acid, including hydrogen chloride, hydrogen bromide, or a mixture thereof, and (c) a catalytic amount of at least one metal-containing compound or complex, under reaction conditions sufficient to form a polymerization reaction product containing a polyaniline polymer. It has been discovered that the processes described herein provide means to prepare polyaniline having a relatively high conductivity at a high degree of aniline monomer conversion using hydrogen peroxide as an oxidant.
