The repeat units of a polybenzoxazine comprise at least one unit corresponding to the formulae (I) or (II): in which Zrepresents 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; Xand X, which are identical or different, represent O or S; Arand Ar, which are identical or different, represent a substituted or unsubstituted phenylene group; and Zrepresents O or (S), 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.
