ABSTRACT:
Diamidopolyamines are prepared by reacting glutamic acid with two moles, per mole of glutamic acid, of a defined class of diamines, including oxyethyelene diamines, oxypropylenediamines, oxyethylene/propylene diamines, oxypropylene triamines, 1,2-diaminocyclohexane and isophorone diamine, whereby each of the carboxyl groups of the glutamic acid will react with an amine group of the amine reactant to thereby provide primary amine terminated amidopolyamines containing, internally, the unreacted primary amine group of the glutamic acid.
