Polyalkylene succinimides and post-treated derivatives thereof

摘要

A succinimide composition is prepared by reacting a mixture of a polyalkenyl derivative, an unsaturated acidic reagent copolymer, and a polyamine under reactive conditions. The polyalkenyl derivative is produced by reacting an unsaturated acidic reagent with a polyalkene in the presence of a strong acid. The unsaturated acidic reagent copolymer is a copolymer of an unsaturated acidic reagent and an olefin.
