A composite structure and method therefor comprises a metal surface which is coated with a polymer incorporating a bidentate chelating functionality. The polymer provides significant and varied chemical modification to the metal surface and is useful, for example, as a protective coating or a priming layer. Bidentate chelating monomers useful in preparing homopolymers and copolymers with ethylenically-unsaturated non-chelating monomers have structures described by the formula ##STR1## in which R.sup.1 is hydrogen, lower alkyl, chlorinated lower alkyl, CN, or Cl P is a connecting linkage of chain length up to to about 75 atoms, and Q is a bidentate chelating group having a high affinity for the ions of the metal of the surface involved.
