Abstract:
A polymer-coated metal composite produced by:providing an acidic starting solution consisting essentially of a first monomer and a second monomer and at least one solvent which dissolves or forms an emulsion of the first and second monomers, wherein the first monomer is 4-carboxyphenyl maleimide, and the second monomer is selected from the group consisting of N-phenyl maleimide, 2-(methacryloyloxy)ethyl acetoacetate, methyl methacrylate and acrylonitrile, and further wherein the first and second monomers are polymerizable on the surface of a metal substrate upon contact with the metal substrate in the absence of other catalyst or catalysts; dipping the metal substrate into the starting solution; and leaving the metal substrate in the starting solution for a time effective to form a polymeric coating by polymerization which occurs on the metal substrate upon contact with the metal substrate in the absence of other catalyst or catalysts.
