Polymeric products comprising the acidified reaction product of an organic polyepoxide and a polyamine containing at least two tertiary amine groups are disclosed. The polyamine and the organic polyepoxide are reacted with one another under conditions to form an internally ionized, quaternary ammonium salt group-containing polymer which has a high molecular weight, but relatively low equivalent weight. The polyamine is formed by reacting an organic polyisocyanate or organic polycarboxylic acid with an active hydrogen-containing tertiary amine. The reaction product is acidified to form the quaternary ammonium salt groups. Preparing the polyamine in this manner gives one wide latitude in determining the final structure of the polyamine. In effect, one can "tailor make" the polyamine by appropriate selection of reactants and exert a great measure of control over the properties of the final polymeric product. The preferred polymeric products are non-gelled, water-dispersible and electrodepositable on the cathode.
