ABSTRACT:
An imide containing polymeric coating is electrophoretically formed on wire from an emulsion. The emulsion contains a polymer, an organic aprotic solvent for the polymer, an amine, and a polar precipitant in which the polymer is insoluble. The wire is passed through a conductive tube immersed in the solvent while a D.C. current is applied between the tube and the wire. The polymer coating on the wire is then cured.
