ABSTRACT:
A process for production of a modified carbon black, at a cheaper cost, for rubber reinforcement having the superior tan δ temperature dependence of silica and an excellent abrasion resistance and further having no problems arising due to a low electrical conductivity is provided granulating the carbon black, after or while adding a water-dispersed silica to the carbon black in a granulator.
