Abstract: front page image
(EN) The invention relates to a metal or metallised reinforcement, at least part of the surface of which is metal, at least said metal part being coated with a polybenzoxazine containing repeating units comprising at least one motif of formula (I) or (II) in which Z1 and Z2 are the same or different and represent an at least divalent, aliphatic, cycloaliphatic or aromatic linking group comprising at least one carbon atom and optionally at least one heteroatom selected from O, S, N and P. The invention also relates to the use of such a reinforcement for reinforcing an item made of rubber, particularly a tyre for a motor vehicle.
