  • Bidentate chelating monomers and polymers
    Patent number: 5385997
    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.
    Type: Grant
    Filed: April 5, 1991
    Date of Patent: January 31, 1995
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Gavin M. Buchan, Ian J. Ferguson
