Patents by Inventor Sonny Jönsson

Sonny Jönsson 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).

  • Free radical polymerization method having reduced premature termination, apparatus for performing the method and product formed thereby
    Patent number: 6908586
    Abstract: A method of polymerizing by a free radical polymerization mechanism, product formed thereby, and apparatus for performing this method, are disclosed. The composition to be polymerized by the free radical polymerization mechanism is irradiated by a substantially constant radiation, the radiation being substantially without pulsation. The use of the substantially constant radiation without pulsation reduces premature termination of the polymerization. The substantially constant radiation can be the output of a lamp powered by a constant current, direct current power supply.

    Date of Patent: June 21, 2005
    Assignee: Fusion UV Systems, Inc.
    Inventors: Jeffrey K. Okamitsu, A. David P. Harbourne, Rong Bao, Sonny Jönsson
  • Polymerization processes using aliphatic maleimides
    Patent number: 6855745
    Abstract: Aliphatic maleimides and methods using the same are disclosed. Polymerization of compositions which include the compounds of the invention may be activated by irradiating the composition with radiation.
    Type: Grant
    Filed: October 8, 2001
    Date of Patent: February 15, 2005
    Assignees: Albemarle Corporation, University of Southern Mississippi
