  • Recovery of monomer from polyurethane materials by depolymerization
    Patent number: 10160741
    Abstract: Methods for recovering monomers from polymers, such as polyurethanes (including thermoset polyurethanes) include heating the polymer to depolymerize the polymer and release the monomer. The monomer may be directly recovered. The polymer may include a poly(?-methyl-?-valerolactone) (PMVL) block and the monomer recovered may be ?-methyl-?-valerolactone (MVL).
    Type: Grant
    Filed: October 10, 2017
    Date of Patent: December 25, 2018
    Assignee: REGENTS OF THE UNIVERSITY OF MINNESOTA
    Inventors: Marc Andrew Hillmyer, Tessie Rose Panthani, Marie Elizabeth Vanderlaan, Deborah Kay Schneiderman, Alexander Michael Rauch Mannion, Derek Charles Batiste, Christopher Ward Macosko, Jay Z. Wang, Frank S. Bates
