    Abstract: Production of polyalkenyl succinimide products (I) by reacting a polyalkene with maleic acid, maleic anhydride or a functional derivative thereof and reacting the resulting polyalkenyl succinic anhydride (II) with an oligo- or polyamine (III). Production of polyalkenyl succinimide products (I) by reacting a polyalkene with maleic acid, maleic anhydride or a functional derivative thereof and reacting the resulting polyalkenyl succinic anhydride (II) with an oligo- or polyamine (III) comprises either (a) reacting (II) with an alcohol or phenol and reacting the product (not isolated) with (III); or (b) reacting (II) with (III) in the presence of an alcohol or phenol; and (c) optionally removing the alcohol or phenol. Independent claims are also included for the following: (1) polyalkenyl succinimide products produced by a process as above; (2) polyalkenyl succinimide products that are produced from a polyalkenyl succinic anhydride and an oligo- or polyamine and contain no more than 30 wt.% of the corresponding polyalkenyl succinamide; (3) polyisobutenyl succinimide products that contain no more than 30 wt.% of the corresponding polyisobutenyl succinamide and are produced from (a) a polyisobutene with a number-average molecular weight (Mn) of 500-10,000 and a terminal double bond content of more than 50 mole%; (b) maleic anhydride; and (c) either a linear, branched, cyclic or cyclic branched alkylene polyamine with 1-10 carbon atoms in each alkylene group and 2-12 nitrogen atoms, at least one of which is present as a primary amine group, or an oligo- or polyamine of formula (IIIa); (4) polyisobutenyl succinic acid monoester products produced from (a) a polyisobutene with a Mn of 500-10,000 and a terminal double bond content of more than 50 mole%; (b) maleic anhydride; and (c) alcohols of formula (IV) or phenols; (5) diesel and gasoline fuel additive packages comprising the products of (1)-(3) and optionally other additives; and (6) lubricant compositions comprising the products of (1)-(3) and optionally other additives. R = 1-16C linear, branched, cyclic or branched cyclic alkyl; x, y = 1-5; z = 0-8.
