FIELD: chemistry.
SUBSTANCE: invention relates to the rubber composition based on diene elastomer, reinforcing filler containing industrial carbon and inorganic filler in an amount which is less than or equal to 50 pts.wt per 100 pts.wt of elastomer. The composition is obtained from the first master batch comprising the first diene elastomer and industrial carbon and containing industrial carbon dispersion in the elastomer matrix with the value of Z, which is greater than or equal to 90. The mother batch is added with an inorganic filler and the second elastomer, which is identical to the first elastomer or different from it.
EFFECT: invention allows to improve the dispersability of fillers in the composition and to improve the hysteresis properties.
