    摘要: The invention relates to a lubricating oil composition with good frictional properties, the composition having a lubricating oil and at least one additive having friction-reducing properties. The additive with friction-reducing properties is a block copolymer having hydrophobic segments P and polar segments D. The hydrophobic segments are obtained by polymerization of monomer compositions having a) between 0 and 40 wt. %, in relation to the weight of the monomer compositions for producing the hydrophobic segments, of at least one ethylenically unsaturated ester compound of formula (I), in which R represents hydrogen or methyl, R1 represents a linear or branched alkyl radical having between 1 and 5 carbon atoms, and R2 and R3 independently represent hydrogen or a group of formula —COOR′, in which R′ represents hydrogen or an alkyl group having between 1 and 5 carbon atoms.

    摘要: The invention relates to lubricating oil formulations comprising copolymers or graft copolymers produced by radically polymerising polymerisable monomers and, in addition comprising long-chain ethylenically unsaturated compounds containing alkyl, in particular acrylate or methacrylate substitutes provided with hydrogen-bridge donator functions. The monomer exhibiting a hydrogen-bridge donator property is contained, according to said invention, in the polymer backbone or in graft side branches. Apart from the polymers containing monomers provided with hydrogen-bridge donator functions, said invention relates to polymers containing monomers simultaneously carrying donator and acceptor functions. It was found that the hydrogen-bridge donator functions of a polymer, in particular a simultaneous availability of the hydrogen-bridge donator and acceptor functions produce the positive effects on the anti-wear protection and on a detergency and dispersancy action. The inventive polymers are suitable, in the form of additives, for lubricating oil formulations, for example for motor oils or hydraulic fluids exhibiting an improved anti-wear behavior.
