    摘要： 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.

    摘要： A process for the preparation of carrier particles which comprises the dry coating of a carrier or carrier cores with conductive submicron polymeric particles containing from about 1 to about 50 weight percent of conductive fillers, and wherein said conductive polymer particles are prepared by mixing at least one monomer with a polymerization initiator, a crosslinking component and a chain transfer component; effecting bulk polymerization until from about 5 to about 50 weight percent of the monomer has been polymerized; terminating polymerization by cooling the partially polymerized monomer; adding thereto from about 1 to about 50 weight percent of a conductive filler or conductive fillers, followed by mixing thereof; dispersing the aforementioned mixture of conductive filler or fillers, and partially polymerized product in water containing a stabilizing component to obtain a suspension of particles with an average diameter of from about 0.05 to about 1 micron in water; polymerizing the resulting suspension by heating; subsequently washing and drying the product; thereafter heating the carrier core or carrier cores and the resulting conductive polymer particles to enable fusing thereof to said core or cores; and cooling the carrier particles obtained, which particles have a conductivity of from between about 10.sup. -4 to about 10.sup.-10 mho-cm.sup.-1.
