MODIFIED DIENE ELASTOMER COMPRISING A DIENE ELASTOMER COUPLED BY AN AMINOALKOXYSILANE COMPOUND AND HAVING AN AMINE FUNCTION AT THE CHAIN END, AND RUBBER COMPOSITION COMPRISING SAME |
| 摘要 |
The invention relates to a modified diene elastomer comprising predominantly the entity functionalized in the middle of the chain by an alkoxysilane group, optionally partially or completely hydrolysed to give silanol, bearing a tertiary amine functional group and the silicon atom of which bonds the two pieces of the chain, the chain ends of the modified diene elastomer being functionalized to at least 70 mol %, with respect to the number of moles of chain end, by an amine functional group. |
