  • Patent number: 8703666
    Abstract: Provided is a method for stabilizing a dispersion of a carbon nanomaterial in a lubricating oil basestock. The method includes providing a lubricating oil basestock; dispersing a carbon nanomaterial in the lubricating oil basestock; and adding at least one block copolymer thereto. The at least one block copolymer has two or more blocks includes at least one alkenylbenzene block and at least one linear alpha olefin block. The at least one block copolymer is present in an amount sufficient to stabilize the dispersion of the carbon nanomaterial in the lubricating oil basestock. Also provided is a lubricating engine oil having a composition including: a lubricating oil base stock; a carbon nanomaterial dispersed in the lubricating oil basestock; and at least one block copolymer.

  • Patent number: 8703678
    Abstract: A grease which comprises a base oil containing at least 50% by mass of a diester compound having a total carbon number of 28 to 40 and represented by the general formula (I): R1OOC—(R2)n—COOR3??(I) wherein R1 and R3 each independently represent a C4 to C20 monovalent aliphatic hydrocarbon group, R2 represents a C1 to C20 divalent hydrocarbon group and n is 0 or 1. The grease is excellent in both low-temperature performance and high-temperature performance and has low oil separation tendency even under high centrifugal force (acceleration). In particular, when the grease is used in a rotational transmission device having a built-in one-way clutch, the grease can provide satisfactory clutch engagement property (intermeshing ability) at low temperatures and a prolonged bearing life at high temperatures and is less apt to cause oil separation under high centrifugal force.

  • Patent number: 8703683
    Abstract: A process for making a poly(alkyl epoxide). The process has the step of polymerizing one or more alkyl epoxide monomers in the presence of a cationic catalyst according to the following sequences: wherein R1, R2, R3, and R4 are hydrogen or alkyl moieties that, taken together, have a total of 1 to 80 carbons; wherein any of R1, R2, R3, and R4 can be linear or branched if it is an alkyl moiety; wherein “m” is an integer from 1 to 4; and wherein “n” is an integer from 2 to 120. There is also another process for making a poly(alkyl epoxide) using an initiator. There are also poly(alkyl epoxides). There is also a lubricant composition having a first lubricant base stock of one or more poly(alkyl epoxides) and a second lubricant base stock different than the first lubricant base stock.
