ABSTRACT:
A process for the preparation of conductive polymeric particles with linear and crosslinked portions, which comprises mixing a monomer with at least one conductive filler, solvent, at least one polymerization initiator, and a chain transfer component; effecting solution polymerization by heating until from about 80 to about 100 weight percent of the monomer has been polymerized; drying the mixture by removing the solvent to yield an intimate blend of polymer with conductive filler; dispersing the aforementioned blend of polymer and conductive filler in at least one monomer with at least one polymerization initiator, a crosslinking agent and a chain transfer agent to form an organic phase; dispersing the resulting organic phase mixture in water containing a stabilizing component to obtain a suspension of particles with an average volume diameter of from about 0.05 to about 5 microns in water; polymerizing the resulting suspension by heating; and subsequently optionally washing and drying the polymeric product.
