  • Low aromatic content bio-mass fillers for free radical and ionic cure thermoset polymers
    Patent number: 10125260
    Abstract: A filled polymer compositions and methods of preparing filled polymer that include a plant biomass filler a plant biomass with a low aromatic carbon content, and (a thermoset polymer. The plant biomass filler may have a low lignin content or no lignin at all. The filler may also be heat treated to a temperature that provides a plant biomass filler with less than 49% aromatic content.
    Type: Grant
    Filed: February 19, 2015
    Date of Patent: November 13, 2018
    Assignee: The University of Akron
    Inventors: Coleen Pugh, Paula Watt, Brinda Mehta
  • Synthesis of cross-linked plant-oil based polymers using bismaleimides as crosslinkers
    Patent number: 10059790
    Abstract: A method of preparing a plant oil based polymer comprising heating a plant oil in the presence of a bismaleimide crosslinker in the substantial absence of a solvent at a temperature at or above the melting temperature of the bismaleimide crosslinker, where the bismaleimide crosslinker is defined by the formula where R1 is a divalent organic group.
