  • Patent number: 9200096
    Abstract: The synthesis of high performance polyvinyl ether (PVE) synthetic fluids using a Lewis acid based cationic polymerization process is disclosed. The polyvinyl ether fluid have repeating vinyl ether units of the general formula —[CH2—CH (O—R)]n, wherein R is comprised of a branched or linear alkyl group having at least 4 carbon atoms and n is a whole number representing the average number of repeating units in the polyvinyl ether. The resulting PVE fluids exhibit excellent lubricant properties, similar to poly-alpha olefins (PAOs), but the PVE fluids have the benefit of higher polarity than PAOs and thus have better solubility and dispersity of polar additives.

  • Patent number: 8293692
    Abstract: The present invention provides a lubricating oil composition comprising at least one type of base oil selected from mineral oils and synthetic oils, and a succinate ester and a sarcosinic acid as rust prevention agents. The succinate ester content is preferably set at 0.01 to 0.1 wt. %, and the sarcosinic acid content is preferably set at 0.001 to 0.01 wt. %. Further, they are preferably set such that the resulting weight ratio of the succinate ester content and sarcosinic acid content is 1:0.01 to 0.7. The lubricating oil composition according to the present invention shows excellent rust prevention properties and a satisfactorily long oxidation lifetime. Further it allows to attain a high level of anti-sludge performance and extreme pressure performance and lubrication performance, even when it is used for example in turbine bearings in combined cycle generators having multiplier gears operated under severe high temperature and high pressure conditions.
