  • Aromatic polyesters from biosuccinic acid
    Patent number: 11059942
    Abstract: Biosuccinic acid, obtained via sugar fermentation, is cyclodimerized and oxidized to yield building blocks for aromatic polyesters with high glass transition temperatures.
    Type: Grant
    Filed: August 21, 2019
    Date of Patent: July 13, 2021
    Assignee: University of Florida Research Foundation, Incorporated
    Inventors: Stephen Albert Miller, Ha Thi Hoang Nguyen, Gabriel Nicholas Short

  • FERULIC ACID AND P-COUMARIC ACID BASED POLYMERS AND COPOLYMERS
    Publication number: 20190002630
    Abstract: A cinnamic acid polymer or copolymer that can be employed as a biorenewable alternative to a commodity polymer results from the polymerization of hydroxyalkyldihydroferulic acids, hydroxyalkylferulic acids, hydroxyalkyldihydrocoumaric acids, hydroxyalkylcoumaric acids, dihydroferulic acid, ferulic acid, dihydrocoumaric acid, and coumaric acid in various proportions. The physical properties of the plastic are controlled by the composition of the polymers. A melt polycondensation route achieves the desired plastics.

  • SILICON/GERMANIUM-BASED NANOPARTICLE PASTES WITH ULTRA LOW METAL CONTAMINATION
    Publication number: 20140179049
    Abstract: Silicon based nanoparticle inks are described with very low metal contamination levels. In particular, metal contamination levels can be established in the parts-per-billion range. The inks of particular interest generally comprise a polymer to influence the ink rheology. Techniques are described that are suitable for purifying polymers soluble in polar solvents, such as alcohols, with respect metal contamination. Very low levels of metal contamination for cellulose polymers are described.
