Abstract:
The repeat units of a polybenzoxazine comprise at least one unit corresponding to the formulae (I) or (II): in which Z 1  represents an at least divalent, aliphatic, cycloaliphatic or aromatic bonding group comprising at least one carbon atom and optionally at least one heteroatom selected from O, S, N and P; X 1  and X 2 , which are identical or different, represent O or S; Ar 1  and Ar 2 , which are identical or different, represent a substituted or unsubstituted phenylene group; and Z 2  represents O or (S) n , the symbol “n” representing an integer equal to 1 or greater than 1. Such a polybenzoxazine can be used as metal-adhesive layer, in particular for the adhesive bonding of a metal substrate, in particular made of carbon steel, to a rubber.

Claim (Index 18):
The polybenzoxazine according to  claim 17 , wherein Z 1  represents an aliphatic group comprising from 1 to 20 carbon atoms or a cycloaliphatic group comprising from 3 to 20 carbon atoms.
