ABSTRACT:
Disclosed is a method of making a non-aqueous emulsion from which a polymer can be electrodeposited. A mixture is prepared of about 50 to about 150 parts by weight of a non-aqueous organic, non-electrolizable, non-solvent for the polymer with about 0.8 to about 1.2 parts by weight of a nitrogen-containing base which can be a tertiary amine, an imidazole, or mixture of a tertiary amine and an imidazole. To the mixture is added a solution of 1 part by weight of the polymer which can be a polyamic acid, a polyamide imide, a polyimide, a polyparabanic acid, a polysulfone, or a mixture of these polymers. The polymer is in a non-aqueous, organic, non-electrolizable aprotic solvent such as N-methyl-2-pyrrolidone.
