PRECOUPLED MONO-SUCCINIMIDE LUBRICATING OIL DISPERSANTS AND VITON SEAL ADDITIVES

摘要

PRECOUPLED MONO-SUCCINIMIDE LUBRICATING OIL DISPERSANT AND VITON SEAL ADDITIVES A lubricating oil composition having improved dispersancy and viton seal compatibility. The dispersant being prepared by coupling two polyethyleneamines with an aldehyde and a phenol,followed by conversion to a succinimide. The resulting coupled succinimide is then acylated with glycolic acid to form a glycolated Mannich phenol coupled mono-alkenyl succinimide.
