ABSTRACT:
This invention is directed to a new low molecular weight branched alkenyl succinic acid derivative that may be prepared by reacting a low molecular weight polyisobutene (PIB) having from about 8 to about 32 carbon atoms, and wherein at least about 50% of the olefinic bonds of the polyisobutene comprises methylvinylidene isomer plus tri-substituted isomer, with an unsaturated acidic reagent and method of making same, resulting in alkenyl succinic acid derivative isomers; and a low molecular weight branched alkenyl succinimide and method of making same.
