ABSTRACT:
Conductive polymeric particles can be formed by mixing a monomer, carbon black and a block copolymer, wherein the block copolymer contains an A block that is miscible with said monomer and a B block that anchors to the surface of the carbon black, such as polystyrene or a derivative of polystyrene. A polymerization initiator is added to the mixture and bulk polymerization is effected until about 5 to about 30 weight percent of the monomer has been polymerized. This partially polymerized product is then dispersed in water and further polymerized.
