  • Stabilized acrylonitrile polymerizations
    Patent number: 5196589
    Abstract: The present invention relates to novel methods of stabilizing polymers of acrylonitrile. The polymers are stabilized by the inclusion of small amounts of stable free radicals compounds which act to inhibit the homopolymerization of the acrylonitrile while promoting the reaction of the acrylonitrile with nucleophilic species such as amines and alcohols.
    Type: Grant

  • Beta branched borate esters
    Patent number: 5171875
    Abstract: The present invention deals with the composition, and application of novel highly branched borate esters, which function as unique oil phases for use in personal care, textile and related applications. The properties of these novel compounds which makes them well suited for these applications is the fact that they are substantive to fibers, hair and skin, are very mild to the skin and eyes. These materials are surprisingly stable to hydrolysis.

  • Guerbet alkyl ether mono amines
    Patent number: 5094667
    Abstract: Distillate fuel compositions containing an alkyl ether mono amine derived from a Guerbet alcohol are effective in reducing the formation of intake valve deposits in internal combustion engines. A preferred alkyl ether mono amine is derived from a highly branched butoxylated Guerbet alcohol containing 20 carbon atoms and having the formulaRO[C.sub.4 H.sub.8 O].sub.(4-8) CH.sub.2 CH.sub.2 CH.sub.2 NH.sub.2where R is a highly branched alkyl group having 20 carbon atoms that is derived from a Guerbet condensation reaction.
    Type: Grant
    Filed: March 20, 1990
    Date of Patent: March 10, 1992
    Assignee: Exxon Research and Engineering Company
    Inventors: Alan M. Schilowitz, James A. Krogh, Anita R. Mokadam, J. Michael Clumpner, Paul J. Berlowitz
  • Branched ether esters as viscosity index modifiers
    Patent number: 5080834
    Abstract: The present invention deals with novel internal branched ether esters based upon novel ether alcohols. These materials are useful as viscosity index modifiers where outstanding liquidity, resistance to oxidation, and minimal variation in viscosity as a function of temperature is required.
    Type: Grant
    Filed: October 18, 1990
    Date of Patent: January 14, 1992
    Assignee: Lce Partnership
    Inventors: J. Michael Clumpner, Anthony J. O'Lenick, Jr.
  • Free radical stabilized alkoxylates
    Patent number: 5010173
    Abstract: The present application relates to a novel method of stabilizing the molecular weight of alkoxylates and stable compositions. The polyoxyalkylene compounds have incorporated into them, from the time of reaction of the alkylene oxide, a free radical type inhibitor which significantly improves stability of both the polymer.
