    摘要: The present invention relates to a lubricant composition containing a base stock and at least 0.01 wt% of a friction reducing additive which is a compound of the Formula (I): R 1 [(AO) n -R 2 ] m (I) wherein R 1 is the residue of a group having at least 2 active hydrogen atoms; m is at least 2; AO is an alkylene oxide residue; each n is independently from 0 to 100; and each R 2 is independently H or R 3 , where each R 3 is independently a residue of a polyhydroxyalkyl or polyhydroxyalkenyl carboxylic acid, a residue of a hydroxyalkyl or hydroxyalkenyl carboxylic acid and/or a residue of an oligomer of the hydroxyalkyl or hydroxyalkenyl carboxylic acid; and on average at least 0.5 of R 2 groups are R 3 . The lubricant composition is suitable for use in an engine oil, a hydraulic oil or fluid, a gear oil and/or a metal-working fluid.
