  • Methods and systems of graft polymerization on a functionalized substrate
    Patent number: 9676907
    Abstract: Graft polymerization is fulfilled on a functionalized substrate. The functionalized substrate is prepared from a disulfide bond-containing feedstock and has been prepared for polymerization through the introduction of one or more polyfunctional monomers containing a disulfide bond breaking material functional group.
    Type: Grant
    Filed: January 28, 2016
    Date of Patent: June 13, 2017
    Assignee: Aspen Research Corporation
    Inventors: John A. Spevacek, Roger Pearson, Kenneth W. Richards, Kenneth D. Zigrino
