Abstract (en)
[origin: WO2021116401A1] The present application relates to a lubricant composition comprising, based on the total weight of the lubricant composition: - at least one base oil; - 0.005 to 10% by weight of at least one polymeric organic friction modifier; and - 0.005 to 10% by weight of at least one ester which is a product of the esterification reaction between a saturated or unsaturated, linear, cyclic or branched monoalcohol having 1 to 10 carbon atoms and a polycarboxylic acid or between a linear, cyclic or branched polyol and a saturated or unsaturated, linear, cyclic or branched monocarboxylic acid having 1 to 10 carbon atoms, said polymeric organic friction modifier is a compound of formula (I): R1 -[(AO)n.-AO—R2]m (I), wherein R1 is a residue of a group having at least m hydrogen atoms, m being greater than 2; AO is an alkylene oxide residue; n is between 0 and 100; R2 is a hydrogen atom or a C-(O)-R3 group, where R3 is a residue selected from the list consisting of a polyhydroxyalkyl carboxylic acid residue, a polyhydroxyalkenyl carboxylic acid residue, a hydroxyalkyl carboxylic acid residue, a hydroxyalkenyl carboxylic acid residue, a hydroxyalkyl carboxylic acid oligomer residue and a hydroxyalkenyl carboxylic acid oligomer residue; and wherein on average at least two R2 groups are acyl.
