Abstract
A non-ASTM low hysteresis carbon black chemically treated, and surface coated with a compound comprising at least one amine group and at least one thiol group, and/or di- and/or polysulfidic linkage is herein disclosed. The surface modified low hysteresis carbon blacks are post treated to remove excess surface modified compound to form refined surface modified low hysteresis carbon blacks.
