ABSTRACT:
A conducting, non-aqueous, colloidal, polysulfone electrodeposition composition is made by mixing: (1) 1 part polysulfone polymer and 20-37 parts non-aqueous, organic, aprotic solvent for the polysulfone polymer with (2) 0.8-1.2 parts of a nitrogen containing base, to form a polysulfone polymer solution, which is added to (3) 25-150 parts of a non-aqueous, non-solvent for the polysulfone polymer, which is miscible with the aprotic solvent.
