UN PROCEDIMIENTO PARA PREPARAR UN PRODUCTO DE REACCION DE POLIOXIALQUILENPOLIAMINA NO GELIFICADO.

摘要

Ungelled reaction products of polyoxyalkylenepolyamies with monoepoxides and optionally with a polyfunctional material which contains groups capable of reacting with amino and/or hydroxyl groups are disclosed. The reaction products can be neutralized with acid and dispersed in aqueous medium where they are useful as additives for cationic electrodeposition baths to improve surface appearance of electrodeposited coatings.
