Lawrence J. Broutman 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).

  • Chemiluminescence apparatus and method for determining the oxidative stability of polymers
    Patent number: 4350495
    Abstract: A chemiluminescence apparatus and method for determining polymer stability by measuring the intensity of the light emitted during thermal oxidation. The apparatus described in the invention measures the light intensity vs. time from polymers in an oxidative atmosphere. On the basis of this information, important parameters such as induction time and oxidation rate can be obtained. The apparatus has the advantage of simultaneous multi-sample analysis and the mathematical approach enables data computerization.
    Type: Grant

    Date of Patent: September 21, 1982
    Inventors: Lawrence J. Broutman, Boris Rozhansky, Lev Zlatkevich
  • Process for continuous production of thermosetting resinous fibers
    Patent number: 4321221
    Abstract: The preparation of cured thermosetting resinous fibers for extruding a dried novoloc resin in admixture with a crosslinking agent to a gear pump having a spinnerette connected thereto for issuance of the molten resin from the spinnerette into an atomsphere of an acid gas for cure of the resinous fibers issuing from the spinnerette.
