摘要
This invention generally relates to new polyol ester derivatives of polyamines for use as dispersant additives compatible in synthetic ester-based turbo oils. The dispersant additives of the present invention consist of a hydrocarbon acid, a polyol, an amine carrier such as diacid or cyclic anhydride and a polyamine. The hydrocarbon acid makes up the non-polar hydrocarbon portion of the dispersant and the polyamine functions as the polar headgroup. The diacid or cyclic anhydride provides a means for attaching the polar polyamine to the dispersant structure through an amide linkage. Different dispersant structures are obtained by varying the hydrocarbon acid, the polyol and the nature of the polyamine.
