摘要：
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.
