The present invention provides a process for preparing an oil soluble product comprising reacting: (a) an olefin copolymer having a number average molecular weight of more than about 5000 functionalised with an acylating agent; (b) an acylating agent substituted with a hydrocarbyl group having a number average molecular weight of about 350 to about 5000; and (c) a compound selected from the group consisting of (i) a polyamine; (ii) a polyol; and (iii) an aminoalcohol, wherein the oil soluble product has a mole ratio of acylating agents (a) to (b) of 1:greater than 2. The invention further provides the use of the oil soluble product in a lubricating composition for lubricating an internal combustion engine.
