Title: POLYBENZOXAZINE THAT CAN BE USED FOR COATING METAL AND FOR THE BONDING OF SAME TO RUBBER
Abstract:
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.
