Title:
RUBBER COMPOSITION CONTAINING A MODIFIED ELASTOMER, METHOD FOR PREPARING SAME, AND TIRE CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2012/007442
Kind Code:
A9
Abstract:
The invention relates to a rubber composition containing at least one diene elastomer, a reinforcing filler, a chemical cross-linking agent, and a modifying agent selected from among the compounds that include at least one group Q and at least one group A bonded together by at least one, and preferably only one, spacer group Sp, where: Q includes a dipole containing at least one, and preferably only one, nitrogen atom; A includes a combined group including at least one nitrogen atom; and Sp is an atom or a group of atoms forming a bond between Q and A. Said composition exhibits a trade-off between mean-deformation stiffness and elongation at break, as well as improved hysteresis properties, and is therefore particularly suitable for the manufacture of tires in order to improve the trade-off between rolling resistance and resistance to large deformations.
