摘要：
Succinimide derivatives represented by the formula: ##STR1## wherein X is selected from the group consisting of M, ##STR2## wherein R is a hydrocarbon-based group containing from about 8 up to about 35 carbon atoms, R.sub.1 and R.sub.2 are each independently hydrogen or an alkyl group containing up to 8 carbon atoms; R.sub.4 is a hydrocarbon-based group containing up to about 28 carbon atoms; R.sub.4 and R.sub.5 are each independently hydrogen or a hydrocarbon-based group containing up to about 25 carbon atoms; and M is a metal cation.
