Title (EN) POLYBENZOXAZINE THAT CAN BE USED FOR COATING METAL AND FOR THE BONDING OF SAME TO RUBBER
(FR) POLYBENZOXAZINE UTILISABLE POUR LE REVÊTEMENT DE MÉTAL ET SON COLLAGE À DU CAOUTCHOUC
Abstract: front page image
(EN) The invention relates to polybenzoxazine comprising 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 polybenzoxazine as a layer that can adhere to metal, particularly for bonding a metal substrate, particularly consisting of carbon steel, to a rubber.
(FR) Polybenzoxazine dont les unités récurrentes comportent au moins un motif répondant aux formules(I) ou (II): dans lesquelles Z1 et Z2, identiques ou différents, représentent un groupement de liaison au moins divalent, aliphatique, cycloaliphatique ou aromatique, comportant au moins un atome de carbone et optionnellement au moins un hétéroatome choisi parmi O, S, N et P. Utilisation d'une telle polybenzoxazine comme couche adhésive au métal, en particulier pour le collage d'un substrat métallique, en particulier en acier au carbone, à un caoutchouc.
