  • Methods for making renewable and chemically recyclable crosslinked polyester elastomers
    Patent number: 10808084
    Abstract: A method includes reacting a polymer derived from a lactone with a cyclic carbonate compound comprising 2 to 5 cyclic carbonate moieties and a catalyst to form a crosslinked polylactone elastomer.
    Type: Grant
    Filed: September 22, 2017
    Date of Patent: October 20, 2020
    Assignee: Regents of the University of Minnesota
    Inventors: Jacob Paul Brutman, Deborah Kay Schneiderman, Marc Andrew Hillmyer, Guilhem Xavier De Hoe
  • 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
  • Poly(beta-methyl-delta-valerolactone) block polymers
    Patent number: 10077340
    Abstract: Block copolymers include a poly ?-methyl-?-valerolactone (PMVL) block. The PMVL blocks can be formed from biosynthesized ?-methyl-?-valerolactone (MVL). The PMVL block may be formed from biosynthesized ?-methyl-?-valerolactone (MVL) with a 14C/12C ratio greater than zero. The block copolymers can include hard blocks. The block copolymers can be thermoplastic elastomers. The block copolymers may include a polylactic acid (PLA) block.
