ELASTOMÈRE DIÉNIQUE MODIFIÉ COMPRENANT UN ÉLASTOMÈRE DIÉNIQUE COUPLÉ PAR UN COMPOSÉ AMINOALCOXYSILANE ET FONCTIONNALISÉ AMINE EN EXTRÉMITÉ DE CHAÎNE ET COMPOSITION DE CAOUTCHOUC LE COMPRENANT
摘要:
The invention relates to a modified diene elastomer comprising a majority of the species functionalised in the middle of the chain by an alkoxysilane group, optionally partially or completely hydrolysed to silanol, having a tertiary amine function and whereof the silicon atom bonds the two pieces of the chain, the chain ends of the modified diene elastomer being functionalised at least at 70 mol%, relative to the number of moles at the end of the chain, by an amine function.
