Abstract

A method of producing a surface modified low hysteresis carbon black or a refined surface modified low hysteresis carbon black compound includes treating a surface of a low hysteresis carbon black with about 0.1% weight by volume to about 50% weight by volume of surface modifying agent in a solvent, and heat treating the surface of the low hysteresis carbon black following the treatment of the surface with the surface modifying agent to form a surface modified low hysteresis carbon black compound, wherein the surface modifier includes at least one amine group and at least one thiol group and/or di- and/or polysulfidic linkage.
