| abstract |
The invention relates to a modified diene elastomer predominantly comprising the species functionalised in the middle of the chain by an alkoxysilane group, optionally partially or completely hydrolysed to silanol, having an epoxide 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. |
