Timothy E. Long and the Long Research Group

High-Performance Macromolecules for Advanced Technologies

The Office of the Vice President for Research and Innovation recognize professor Timothy E. Long and his research group from the Department of Chemistry as Inventors of the Month for September 2017 for their continued development of high-performance macromolecules for advanced technologies.

During the 2017 fiscal year, Long and his group disclosed the following inventions to VTIP:

  • Sulfonate-endcapped Long-chain Branched Poly(ether imide)s
  • Liquid Crystal Polyesters Ureido-pyrimidinone (UPy) End-capped Telechelic Polyetherimide Oligomers for Solution-processable Polyetherimides
  • 3D Printing All-Aromatic, High Performance Polyimides and Polybenzoxazoles Using Stereolithography (SLA): Processing the Unprocessable
  • Printing of Actives Within a Water Soluble Ionic PEG
  • Copolyesters Containing 4,4'-Biphenyldicarboxylate or 3,4'-Biphenyldicarboxylate and Two or More Diols
  • Amorphous Copolyesters Containing 4,4'-Biphenyldicarboxylate and/or 3,4'-Biphenyldicarboxylate and/or Terephthalate or Isophthalate Units with NPG or CHDM

Each of these inventions has different specific properties that have generated licensing interest from the industry research sponsors, including Exxon Mobil, Procter & Gamble, Solvay, Evonik Industries, Phillip Morris, 3D Systems, and Saudi Basic Industries Corporation. In general, the Long Group seeks to design novel polymers for global impact on everything from consumer products to biomedical devices. This mission has led to collaborations across the university with coinventors such as Chris Williams of Mechanical Engineering and Richard Turner of the Macromolecules Innovation Institute. Numerous graduate students and posdoctoral researchers are also coinventors of the inventions listed above.
