Abstract:
A process for producing a self-metallizing, reflective polyimide film which is flexible, abrasion-resistant, and thermally stable, which process comprises:reacting an aromatic dianhydride with an aromatic diamine in a solvent to produce a polyamic acid solution;combining silver(I) acetate with an effective amount of a solubilizing agent therefor in the solvent to yield solubilized silver(I) acetate;doping the polyamic acid solution with the solubilized silver(I) acetate;preparing a film from the polyamic acid solution which has been doped with the solubilized silver(I) acetate; andcuring the film to convert the polyamic acid to the corresponding polyimide and reduce the solubilized silver(I) acetate to metallic silver.
