  • Patent number: 8722600
    Abstract: 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.

  • Patent number: 7358216
    Abstract: A process is disclosed for manufacturing a lubricant composition comprising combining a superabsorbent polymer with a material for decreasing friction between moving surfaces. The superabsorbent polymer absorbs from about 25 to greater than 100 times its weight in water and may comprise a polymer of acrylic acid, an acrylic ester, acrylonitrile or acrylamide, including co-polymers thereof or starch graft co-polymers thereof or mixtures thereof. A product produced by the process includes the material for decreasing friction comprising a petroleum lubricant containing an additive, water containing an additive, synthetic lubricant, grease, solid lubricant or metal working lubricant, wherein the synthetic lubricant, grease, solid lubricant or metal working lubricant optionally contain an additive. A process comprising controlling the delivery of a lubricant to at least one of two moving surfaces in order to decrease friction between said moving surfaces, is also disclosed.
