MODIFIED DIENE ELASTOMER AND RUBBER COMPOSITION CONTAINING SAME |
| 摘要 |
A modified diene elastomer, a process of preparing the elastomer is provided. The modified diene elastomer comprises:
(i) from 40 to 80% by weight of the entity functionalized at the chain end by an alkylalkoxysilane group, optionally partially or completely hydrolysed to give silanol, bearing a primary, secondary or tertiary amine function, and bonded to the elastomer via the silicon atom,(ii) from 5 to 45% by weight of the entity functionalized in the middle of the chain by an alkoxysilane group, optionally partially or completely hydrolysed to give silanol, bearing a primary, secondary or tertiary amine function, and the silicon atom of which bonds the two pieces of the chain,(iii) from 3 to 30% by weight of the three-branch star-branched entity containing a silane functional group, bearing a primary, secondary or tertiary amine function, and the silicon atom of which bonds the three branches of the chain. |

1. A modified diene elastomer comprising:
(i) from 40 to 80% by weight, with respect to the total weight of the said modified diene elastomer, of the entity functionalized at the chain end by an alkylalkoxysilane group, optionally partially or completely hydrolysed to give silanol, bearing a primary, secondary or tertiary amine function, and bonded to the elastomer via the silicon atom, (ii) from 5 to 45% by weight, with respect to the total weight of the said modified diene elastomer, of the entity functionalized in the middle of the chain by an alkoxysilane group, optionally partially or completely hydrolysed to give silanol, bearing a primary, secondary or tertiary amine function, and the silicon atom of which bonds the two pieces of the chain, (iii) from 3 to 30% by weight, with respect to the total weight of the said modified diene elastomer, of the three-branch star-branched entity containing a silane functional group, bearing a primary, secondary or tertiary amine function, and the silicon atom of which bonds the three branches of the chain. |
