  • Patent number: 9611380
    Abstract: The invention relates to a rubber composition based on at least one diene elastomer, a reinforcing filler comprising at least carbon black and an inorganic filler with an inorganic filler content of less than or equal to 50 parts by weight per hundred parts of elastomer, characterized in that the composition is obtained from a first masterbatch comprising at least one first diene elastomer and carbon black, and having a dispersion of the carbon black in the elastomeric matrix that has a Z value of greater than or equal to 90, added to which is the inorganic filler and at least one second elastomer, identical to or different from the first elastomer, and also to the process for preparing such a composition.
