In-situ formation of a diprimary amine curing agent
 Reactions involving diprimary amines, e.g., methylenedianiline, particularly those forming polyesterimides are carried out using, in place of the diamine, a urethane compound capable of yielding the diamine at reaction temperatures. The preparation of wire enamels from polyesterimides thus prepared is particularly described.
