Abstract

A succinimide composition is prepared by reacting a mixture of an alkenyl or alkylsuccinic acid derivative, an unsaturated acidic reagent copolymer, and a polyamine under reactive conditions. The alkenyl or alkyl substituent of the alkeny or alkylsuccinic acid derivative has a Mn of from 1000 to 5000. The unsaturated acidic reagent copolymer is a copolymer of an unsaturated acidic reagent and an alkylene group. That alkylene group can be an .alpha.-olefin having 8 to 42 carton atoms, a polyalkylene having from 8 to 28 carbon atoms, ethylene, styrene, 1,3-butadiene, vinyl alkyl ether having at least 3 carbon atoms, or vinyl alkanoate having at least 4 carbon atoms. The polyamine has at least three nitrogen atoms and 4 to 20 carbon atoms. The mixture contains from 0.5 to 10 equivalents of the alkenyl or alkylsuccinic acid derivative per equivalent of unsaturated acidic reagent copolymer and from 0.4 to 1.0 moles of polyamine per equivalent of alkenyl or alkylsuccinic acid derivative plus unsaturated acidic reagent copolymer.
