(57) [Summary]nA method for producing a carbon black product having an organic group bonded to carbon black. In one process, carbon black is reacted with at least one diazonium salt in the absence of an externally applied current sufficient to reduce the diazonium salt. In another process, carbon black is reacted with at least one diazonium salt in the presence of a protic reaction medium. Disclosed are carbon black products that can be produced by the process of the present invention, and the use of such carbon black in plastic, rubber, paper, and fiber compositions. |
