Abstract (en)
[origin: WO2017089708A1] The present invention relates to the use of a diene elastomer and a 1,3-dipolar compound in a rubber composition made up of at least one reinforcing filler comprising a reinforcing inorganic filler and a coupling agent, the 1,3-dipolar compound comprising a Q group and an A group connected together by a B group, in which Q comprises a dipole containing at least, and preferably, one nitrogen atom, A comprises an associative group comprising at least one nitrogen atom, and B is an atom or a group of atoms forming a bond between Q and A, the diene elastomer being obtained by stereospecific polymerisation of at least one 1,3-diene by means of a Ziegler-Natta catalytic system and containing less than 150 ppm of the element neodymium. The use of such a diene elastomer and such a 1,3-dipolar compound in the rubber composition makes it possible to ensure very low hysteresis of the rubber composition.
