摘要：
The invention provides alkenyl succinimide derivatives, useful as dispersant additives in lubricating oil compositions, having an alkenyl group derived from an atactic propylene oligomer substantially of the formula
where n is in the range 15 to 120, having number average molecular weight (M n ) in the range 700 to 5000, and molar ratio succinic acid moieties : atactic propylene oligomer in the range 1:1 to 1.5:1, wherein the succinimide is derived from a C₁₋₅₀ amine; a process for their preparation; and lubricating compositions containing them.
