Procedure

A succinimide of a polyoxypropylenediamine of about 2000 MW(JEFFAMINE® D-2000) is prepared as follows: A mixture of JEFFAMINE® D-2000 (750 g., 0.375 mole) and maleic anhydride (18.4 g., 0.187 mole) was refluxed in benzene until water removal was complete (reaction temperature 145°-195° C.). The resulting product was then vacuum stripped at 180° C./3 MM. The product analyzed as follows--total amine 0.64 meq./g., primary amine 0.43 meq./g.
