Rubber composition based on at least one functionalized elastomer comprising polar functional groups and a specific polyphenolic compound

A rubber composition based on at least one functionalized elastomer comprising polar functional groups, a reinforcing filler and a polyphenolic compound comprising at least three aromatic rings comprising 6 carbon atoms, each bearing at least two vicinal hydroxyl groups,

• 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.
