Chemically surface modified carbon black and methods of making same

An unrefined surface modified low hysteresis carbon black (SMLHCB) or a refined surface modified low hysteresis carbon black (SMLHCB-R) compound, comprising:

• a non-oxidized low hysteresis carbon black having wide aggregate size distribution with higher percentage of larger aggregates than a standard ASTM grade carbon black and aggregates size of the non-oxidized low hysteresis carbon black is a range from 0.005 micrometers to about 1.0 micrometers, the non-oxidized low hysteresis carbon black having a surface modified to have a surface modifier attached thereto, wherein the surface modifier comprises at least one amine group and at least one thiol group and/or disulfidic di- and/or polysulfidic linkage thereof, wherein the surface modifier is attached on a fraction of the surface of the non-oxidized low hysteresis carbon black at discrete, spaced apart regions of the surface of the non-oxidized low hysteresis carbon black, wherein the surface modifier comprises an amino acidic compound or a derivative of the amino acidic compound.
