FIELD: organic chemistry, rubber industry. ^ SUBSTANCE: carbon black is treated with at least one quinonediimine compound described by the formula (IIIa) or (IIIb) wherein R1 and R2 are taken independently among alkyl, alkenyl, cycloalkyl, aryl, aralkyl and alkaryl wherein alkyl fragments in groups R1 and R2 are linear or branched, and each group among R1 and R2 can be substituted; R3, R4, R5 and R6 are similar or different and taken among hydrogen atom, alkyl, alkenyl, cycloalkyl, aryl, aralkyl and alkaryl wherein alkyl fragments in groups R3, R4, R5 and R6 are linear or branched and each group among R3, R4, R5 and R6 can be substituted. The treatment temperature is above melting point of indicated compound but lower of its decomposition point. Treated carbon black is dispersed in composition comprising natural or synthetic polymers, mainly, elastomers, plastics or their mixtures. Invention provides enhancing dispersing capacity of carbon black and decreasing the composition viscosity. Invention can be used in preparing rubber compositions. ^ EFFECT: improved and valuable properties of carbon black and compositions. ^ 11 cl, 9 tbl, 4 ex |
