| titleOfInvention | Rubber compositions based on modified diene elastomers |
| abstract | The present invention relates to a rubber composition based on at least one reinforcing filler having a silica content of greater than or equal to 80 phr, preferably greater than or equal to 100 phr, and an elastomeric matrix, the elastomeric matrix having A modified diene elastomer having a content of greater than or equal to 75 phr, said modified diene elastomer comprising macromolecules comprising linear or branched polyether blocks within their structure, whereby The polyether blocks comprise branch points at each of the two ends of the block, the branch points being bonded to up to three diene elastomer branches and up to three -OR groups, R to each other Representing independently C1-C8 alkyl substituents or hydrogen atoms, a-copolymers have a Mooney viscosity of at least 30, preferably at least 40 and at most 100, b-copolymers consisting of:- at least 20%, preferably at least 30% branched macromolecules comprising polyether blocks bonded to at least three diene elastomer blocks, - up to 80%, preferably up to 70% linear macromolecules, c - The polyether blocks have a number-average molecular weight of from 150 g/mol to 5000 g/mol, and d- each branch point consists of silicon atoms. |
