Publication number: 20160362504Abstract: The present invention relates to a modified diene elastomer predominantly comprising a species coupled via a group bearing a function comprising a silicon atom predominantly hydrolysed into silanol and a tertiary amine function, linked to the diene elastomer via the silicon atom, and to the process for synthesizing the modified diene elastomer. This elastomer has the particular feature of not undergoing any change in Mooney viscosity during its storage.Type: ApplicationFiled: July 11, 2014Publication date: December 15, 2016Applicants: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELIN, MICHELIN RECHERCHE ET TECHNIQUE, S.A.Inventors: Charlotte DIRE, Jean-Mark MARECHAL, Margarita DORATO, Mathieu MANCEAU, Nuno PACHECO
