  • Electrostatic deposition of high temperature, high performance liquid crystalline polymers
    Patent number: 6761834
    Abstract: A process to produce a liquid crystalline polymer film comprises electrostatically depositing a fine powder of liquid crystalline polymer resin onto a carrier and fusing the deposited fine powder to form a liquid crystalline polymer film that is isotropic in the x-y plane. The electrostatic deposition of the resin particles results in a substantially random molecular alignment of the liquid crystalline polymer. The carrier can comprise an all metal foil, a metal foil laminate, a polymer film material, or a release material.
    Type: Grant
    Filed: September 20, 2001
    Date of Patent: July 13, 2004
    Assignee: World Properties, Inc.
    Inventors: Michael St. Lawrence, Ki-Soo Kim, Saroj Roy

  • Method for synthesizing 2'-O-substituted pyrimidine nucleosides
    Patent number: 5739314
    Abstract: The present invention provides an improved method of synthesizing 2'-O--R substituted pyrimidine mononucleosides. The method comprises reacting an anhydropyrimidine with magnesium alkoxide in the corresponding alcohol at elevated temperatures to directly produce the 2'-O--R substituted pyrimidine nucleoside product. The method advantageously eliminates several steps from prior art methods, thereby reducing the time and cost of synthesis and increasing the yield of final product.
