Abstract
Novel, linear, film-forming polymers and copolymers can be coated on certain metal surfaces, which polymers or copolymers are derived from one or more classes of ethylenically-unsaturated monomers and include at least one novel monomer having a bidentate chelating moiety. The polymers which contain bidentate chelating groups provide significant and varied chemical modification to a metal surface. When coated on a metal surface the polymers are useful as a protective coating or a priming layer.
