A metal or metallized reinforcer, at least the surface of which is at least partially metallic, comprises at least a metallic part coated with a polybenzoxazine, the repeat units of which comprise at least one unit corresponding to the formulae (I) or (II): ##STR00001##
in which Z.sub.1 and Z.sub.2, which are identical or different, represent 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. Such a reinforcement can be used for the reinforcement of a rubber article, in particular a motor vehicle tire.

The present disclosure relates to a process of manufacturing curable precursor of a structural adhesive composition. According to another aspect, the present disclosure is directed to method of bonding two parts.

The present invention relates to an adhesive aqueous composition comprising a polysaccharide or a residual fraction from a pulping process comprising polysaccharide and an amine-functional polymer. The weight ratio between the polysaccharide and the amine-functional polymer is from 1:4 to 4:1; wherein the polysaccharideis hemicellulose or gum and with proviso that the composition has a pH of 6 or less when the amine-functional polymer is chitosan.
