Claim 1

A NITROGEN-CONTAINING COMPOSITION PREPARED BY THE PROCESS COMPRISING MIXING AT A TEMPERATURE FROM ABOUT 0*C. UP TO ABOUT 100*C. (A) ONE EQUIVALENT OF AN ACIDIC REACTANT PREPARED BY PARTIALLY ESTERIFYING A SUCCINIC ACID COMPOUND SELECTED FROM THE CLASS CONSISTING OF ALKENYLSUCCINIC ACIDS HAVING AT LEAST ABOUT 8 CARBON ATOMS IN THE ALKENYL GROUP AND THE ANHYDRIDES OF SAID ACIDS WITH FROM ABOUT 0.1 TO ABOUT 0.5 MOLE OF A COMPOUND SELECTED FROM THE CLASS CONSISTING OF ALKYLENE OXIDES HAVING UP TO ABOUT 8 CARBON ATOMS, EPIHALOHYDRINS HAVING UP TO ABOUT 8 CARBON ATOMS, AND POLYHYDRIC ALCOHOLS HAVING UP TO ABOUT 8 CARBON ATOMS, AND (B) FROM ABOUT 1 TO 3 EQUIVALENTS OF A BASIC REACTANT PREPARED BY PARTIALLY ACYLATING AT A TEMPERATURE ABOVE ABOUT 100*C. AN ALKYLENE POLYAMINE WITH UP TO ONE LESS EQUIVALENT THAN THE NUMBER OF AMINO GROUPS IN SAID POLYAMINE OF AN ALIPHATIC HYDROCARBON CARBOXYLIC ACID HAVING AT LEAST ABOUT 12 CARBON ATOMS AND TREATING THE PARTIALLY ACYLATED POLYAMINE WITH FROM ABOUT 0.5 TO ABOUT 5% BY WEIGHT OF AN ALKYLENE EPOXIDE HAVING UP TO ABOUT 8 CARBON ATOMS AT A TEMPERATURE ABOVE ABOUT 100*C.
