Abstract
A tire comprises a rubber composition based on at least one diene elastomer, a reinforcing filler predominantly comprising silica, a crosslinking system, and an amino ether alcohol of formula (I): R1—O(—R2—O)n—R3—NH2 (I), in which R1 represents a linear or branched alkyl group comprising from 1 to 18 carbon atoms, R2 and R3 independently represent a linear or branched alkylene group comprising from 1 to 18 carbon atoms, and n represents an integer from 0 to 20, it being understood that the amino ether alcohol bears one or more hydroxyl groups on at least one carbon-based chain chosen from R1, R2 and R3. The rubber composition is essentially devoid of guanidine derivative.
Claims45
A tire comprising a rubber composition based on:
- at least one diene elastomer,
- a reinforcing filler comprising silica, where a content of silica is greater than a content of any other reinforcing filler that may be present,
- a crosslinking system, and
- an amino ether alcohol of formula (I):
- R1—O(—R2—O)n—R3—NH2 (I)
- in which R1 represents a linear or branched alkyl group comprising from 1 to 18 carbon atoms, R2 and R3 independently represent a linear or branched alkylene group comprising from 1 to 18 carbon atoms, and n represents an integer from 0 to 20,
- wherein the amino ether alcohol of formula (I) bears one or more hydroxyl groups on at least one of R1, R2 and R3,
- wherein the rubber composition includes less than 0.5 phr of guanidine derivative.
