ABSTRACT:
Disclosed are polyaminoalkenyl or alkyl succinimides which have been modified by treatment with a compound of the formula: ##STR1## wherein W is oxygen or sulfur; X is oxygen or sulfur; R.sub.4 is an alkylene group of from 2 to 3 carbon atoms or an alkylene group of from 2 to 3 carbon atoms substituted with from 1 to 3 alkyl groups of from 1 to 2 carbon atoms each; and R.sub.5 is hydrogen or alkyl of from 1 to 20 carbon atoms. The modified polyamino alkenyl or alkyl succinimides of this invention have been found to possess dispersancy and detergency in lubricating oils. These modified succinimides are also useful as dispersants and detergents in fuels.
