    Abstract: An aziridine detergent-dispersant derivative, lube oil compositions containing said derivative, and manufacture thereof, said derivative being the reaction product of an aziridine of the formula:

    WHERE R is hydrogen or omega -aminoalkyl of from 1 to 5 carbons and a monoethoxylated hydrolyzed polyalkene-P2S5 reactant, said derivative prepared by: A. FIRST CONTACTING AN ALIPHATIC POLYALKENE OF AN AVERAGE MOLECULAR WEIGHT OF BETWEEN ABOUT 50 AND 5,000 WITH P2S5 in the presence of sulfur at a first elevated temperature, B. SECOND CONTACTING THE RESULTING POLYALKENE-P2S5 reaction product with steam at a second elevated temperature, C. REMOVING INORGANIC PHOSPHORUS ACID FROM THE STEAM TREATED (HYDROLYZED) POLYALKENE-P2S5 reaction product, D. THIRD CONTACTING THE INORGANIC ACID FREE, STEAM TREATED POLYALKENE-P2S5 reaction product with ethylene oxide at a third elevated temperature in a mole ratio of said inorganic phosphorus acid free, steam treated P2S5-polyalkene reaction product to said ethylene oxide of between about 1:1 and 1:1.5 to form said monoethoxylated reactant, E. FOURTH CONTACTING THE ETHOXYLATED DERIVATIVE WITH SAID AZIRIDINE AT A FOURTH ELEVATED TEMPERATURE UTILIZING A MOLE RATIO OF SAID DERIVATIVE TO SAID AZIRIDINE OF BETWEEN ABOUT 3:1 AND 1:2 TO FORM SAID DETERGENT-DISPERSANT DERIVATIVE.
