Conductive polymers are prepared from a stabilized solution containing a monomer, an Fe(III) oxidizing agent, and a mixed solvent. The solvents are selected to stabilize the Fe(III) oxidizing agent and monomer in solution while allowing highly conducting polymers to be produced upon evaporating the lower-boiling solvent. The higher-boiling solvent does not appreciably complex with Fe(III), while the lower-boiling solvent forms a weak complex with Fe(III). The mixed-solvent system of the present invention may be used for preparing a conductive polymer counter electrode in a solid tantalum capacitor by polymerizing the monomer inside a porous tantalum pellet.

[ What is claimed is:] [1.] A process for preparing a conductive polymer from a stabilized precursor solution comprising:(a) dissolving a monomer and an Fe(III) oxidizing agent in a mixed solvent, the mixed solvent comprising a first solvent having a first boiling point, wherein the first solvent does not appreciably complex with Fe(III), and a second solvent having a second boiling point which is lower than the first boiling point, wherein the second solvent forms a weak complex with Fe(III);(b) evaporating the second solvent; and(c) reacting the monomer and oxidizing agent to produce a conductive polymer.
