ABSTRACT:
A method is provided for making stable electrocoatable polyimide mixtures having a high water content. A solution of polyimide in a dipolar aprotic solvent is heated in the presence of base resulting in a transitory viscosity decrease. Major amounts of water can thereafter be added to the mixture during its reduced viscosity state to produce a stable aqueous mixture.
