Abstract
A rubber composition based at least on a functional elastomer and a reinforcing filler which comprises a carbon black is provided. The functional elastomer is a diene elastomer which comprises diene units in the cis-1,4 configuration and pendant groups of formula (I). The Y, Y, Yand Ysymbols, which are identical or different, represent an atom or a group of atoms, and at least one of the symbols denotes an attachment to a diene unit of the elastomer. The diene units in the cis-1,4 configuration represent at least 90 mol % of the diene units of the functional elastomer, and the carbon black represents more than 50% by weight of the reinforcing filler.
