Abstract

Disclosed is a method for preparing conductive carbon black by combining a polymer and carbon black by shear mixing at elevated temperatures and pressures in order that the carbon particles are fused into the melted surface of a polymer such as styrene/n-butyl methacrylate. In one embodiment, the shear mixing can be

Disclosed is a method for preparing conductive carbon black by combining a polymer and carbon black by shear mixing at elevated temperatures and pressures in order that the carbon particles are fused into the melted surface of a polymer such as styrene/n~butyl methacrylate. In one embodiment, the shear mixing can be

accomplished in rubber mills. The resultant material is useful in a toner composition for magnetic development.
