Desmond Austin Young has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polymerization
    Publication number: 20030008988
    Abstract: A polymer of ethylene as a first monomeric component, with a high carbon number linear alpha olefin having at least five carbon atoms as a second monomeric component. At least one of the monomeric components is Fischer-Tropsch derived so that it includes at least one other olefinic component. A process for producing the polymer is also provided.

    Applicant: SASOL TECHNOLOGY (PROPRIETARY) LIMITED
    Inventors: Ioan Tincul, Dawid Johannes Joubert, Desmond Austin Young
  • Waxes
    Patent number: 6362377
    Abstract: A process for modifying a wax comprising treating a wax to introduce a hydroxyl functionality, said treating being selected from the group consisting of grafting with an allyl alcohol, oxidizing the wax and hydrogenating the oxidized wax, reacting the wax with a peroxide and mixtures thereof, so as to form primary and/or secondary hydroxyl groups thereon, thereby to obtain a hydroxyl wax; and subjecting at least some of the hydroxyl groups of hydroxyl wax to alkoxylation to form a modified wax.
    Type: Grant
    Filed: March 14, 2000
    Date of Patent: March 26, 2002
    Assignee: Schumann-Sasol (Proprietary) Limited
    Inventors: Desmond Austin Young, Michelle Grant, Stefanus Johannes Strydom, Jacobus Lucas Visagie, Christiaan Frederick Reinecke, Nicolaas Russouw Louw
  • Polymerization of copolymers of ethylene/propylene with higher olefins
    Publication number: 20020026017
    Abstract: A polymer obtained from a first olefin having fewer than 4 carbon atoms, and a second olefin having a total number of carbon atoms greater than 5 and having an uneven number of carbon atoms. The molar proportion of the first olefin to the second olefin in the polymer is from 90:10 to 99.9:0.1. A process for producing the polymer is also provided.
    Type: Application
    Filed: May 23, 2001
    Publication date: February 28, 2002
    Applicant: SASOL TECHNOLOGY (PTY) LIMITED
    Inventors: Ioan Tincul, Dawid Johannes Joubert, Ignatius Hendrik Potgieter, Desmond Austin Young
  • Ethylene terpolymers and process for their preparation
    Publication number: 20010025091
    Abstract: The invention provides a polymer of ethylene as a first component or monomer, with a branched olefin as a second component or monomer, and at least one different olefin as a third component or monomer. The olefins can be obtained from a Fischer-Tropsch process.
