    摘要: A lubricant composition comprising, in relation to 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, said polymeric organic friction modifier being the reaction product of: a) at least one hydrophobic polymer subunit which comprises a hydrophobic polymer selected from polyolefins, polyacrylics and polystyrenes; b) at least one hydrophilic polymer subunit which comprises a hydrophilic polymer selected from polyethers, polyesters and polyamides; c) optionally at least one backbone moiety capable of linking polymeric subunits together; and d) optionally a chain termination group.
