  • Method of suppressing mist formation from oil-containing functional fluids
    Patent number: 5329055
    Abstract: There is disclosed a method of suppressing misting or spatting from an oil-containing functional fluid, such as a chain saw lubricant, by blending with the functional fluid a mist suppressing effective amount of a copolymer of a C.sub.3 or C.sub.4 alpha-monoolefin and at least one other alpha-monoolefin having from 5 to about 20 carbon atoms, said copolymer having a viscosity average molecular weight of from about 500,000 to about 10 million.
    Type: Grant
    Filed: May 14, 1993
    Date of Patent: July 12, 1994
    Assignee: Exxon Chemical Patents Inc.
    Inventors: Harold E. Bachman, Chung K. Shih
  • Synergistic blend of amine/amide and ester/alcohol friction modifying agents for improved fuel economy of an internal combustion engine
    Patent number: 5282990
    Abstract: The fuel economy of an internal combustion engine can be improved by adding to the lubricating oil used to lubricate the crankcase of said engine a synergistic blend of amine/amide and ester/alcohol friction modifying agents, for example, by reacting (a) a carboxylic acid, such as oleic acid and/or isostearic acid with an amine, such as diethylene triamine or tetraethylene pentamine, and (b) glycerine monooleate and/or glycerine monoricinoleate.
    Type: Grant
