DIENE ELASTOMER MODIFIED BY COUPLING HAVING SILANOL FUNCTIONS, SYNTHESIS METHOD FOR SAME AND RUBBER COMPOSITION COMPRISING IT

摘要

The present invention relates to a modified diene elastomer comprising a majority of a species coupled by a carrier group with a function comprising a primarily silanol-hydrolysed silicon atom and an amine function, bonded to the diene elastomer by the silicon atom and its synthesis process. This elastomer has the particularity of not undergoing an evolution of the Mooney viscosity when it is stored.
