ABSTRACT:
A process for the preparation of conductive polymers which comprises (a) mixing at least one monomer with at least one conductive component, solvent, at least one polymerization initiator, and an optional chain transfer component; (b) effecting solution polymerization by heating; (c) removing said solvent by azeotropic distillation in an aqueous phase to generate a mixture of polymer and conductive component; (d) drying and grinding the resulting mixture; thereafter dissolving the product resulting in at least one monomer, at least one initiator, and at least one crosslinking component, and an optional chain transfer agent to form an organic phase; (e) mixing said organic phase with a second aqueous phase comprised of water, stabilizer, and an alkali halide; (f) polymerizing the resulting suspension by heating; and (g) subsequently optionally washing and drying the polymeric product, and which product is comprised of polymer and conductive component dispersed therein.
