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; then treating the reaction product with either a cyclic carbonate or a linear mono- or polycarbonate or boron compound under reactive conditions. The alkenyl or alkyl substituent of the alkenyl or alkylsuccinic acid derivative has a Mn of from 1800 to 3000. The unsaturated acidic reagent copolymer has a Mn of from 2000 to 4800, and is a copolymer of an unsaturated acidic reagent and an olefin having an average of from 14 to 30 carbon atoms. The polyamine has at least three nitrogen atoms and 4 to 20 carbon atoms. The mixture contains from 1.5 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.
