1. A rubber composition based on at least one functionalized elastomer comprising polar functional groups, a reinforcing filler and 2-30 phr of a phenolic compound of general formula (I)
![]() in which:
G1 is a hydroxyl, carboxyl or alkoxy group or a hydrogen atom;
G2 is a hydroxyl group or a hydrogen atom;
G3 is a hydrogen atom or a group selected from the group consisting of hydroxyl, carboxyl, hydrogenocarbonyl, alkyl, carboxylalkyl, carboxylalkenyl, carbonylalkyl, aryl, aryloxy, arylthioxy, arylcarbonyl, amino, and aminoalkyl; and
at least one of the substituents G1 to G3 comprises an oxygen atom,
wherein the polar functional groups of the at least one functionalized elastomer comprise at least one group selected from the group consisting of hydroxyl, carbonyl, imine and epoxide groups,
wherein the rubber composition does not comprise molecular sulfur,
wherein the rubber composition does not comprise zinc oxide, and
wherein the rubber composition does not simultaneously comprise an alkyl-imidazole and a polycarboxylic acid of general formula (P1):
![]() in which A is a covalent bond or a hydrocarbon-based group including at least 1 carbon atom, which is optionally substituted and optionally interrupted with one or more heteroatoms.
