Post-treated derivatives of polyalkylene succinimides

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