摘要
A process for the preparation of polyalkenylsuccinimide products, in particular polyisobutenylsuccinimide products, is proposed, in which a polyalkene is reacted with a maleic acid, maleic anhydride or a functional derivative thereof to give a polyalkenylsuccinic anhydride and the polyalkenylsuccinic anhydride is then reacted with an oligoamine or polyamine, the polyalkenylsuccinic anhydride either (a) first being reacted with an alcohol or phenol and, without isolation of the reaction product, then with the oligoamine or polyamine, or (b) the polyalkenylsuccinic anhydride being reacted with the oligoamine or polyamine in the presence of an alcohol or phenol and (c) if desired, the alcohol or the phenol then being removed. Novel polyalkenylsuccinimide products, in particular polyisobutenylsuccinimide products, and fuel additives are also proposed.
