摘要：
Compounds suitable for use as EP/AW additives in lubricating oil compositions which compounds have the formula:-
wherein X is independently either a carboxylic acid group, a carboxylic acid ester group, a hydroxyl group or the group YZ wherein Z = X and Y is either an alkylene, aralkylene or cycloalkene group,
R¹ is an aliphatic hydrocarbyl group, and
R² is either hydrogen, a hydrocarbyl group or the group YZ.
