Abstract: There is prepared a homogeneous mixture of 95 to 30% carbon black and 5 to 70% resorcinol. The resorcinol preferably either has an average particle size of 0.01 to 0.4 mm or is broken down to that size. The product is employed in rubber mixture to improve the adhesion of rubber vulcanizates to metal, textile fibers, glass fibers, or their structures.

Abstract: A process for removing extractables from carbon blacks in a fluidized bed, wherein low extractable carbon blacks are treated under relatively mild temperature conditions (320 DEG C.) with an oxygen containing gas and high extractable carbon blacks are treated first at 100 DEG -320 DEG C. with steam and then at 200 DEG -500 DEG C. with an oxygen containing gas. A definition of classification in the "low extractable" and "high extractable" categories is given.
