  • Patent number: 10549475
    Abstract: The present invention discloses a method for preparing stable 3D polymer objects with surface micro-nanostructures. The method includes the following steps: Step (1): Synthesizing a thermoset 2D polymer object with surface microstructures. The polymer network contains reversible exchangeable bonds. Step (2): deforming synthesized polymer to an arbitrary desired shape above the reshaping temperature with an external force applied. The permanent reshaping temperature falls in the range of 50-130° C. and external stress is held for 5 min-24 hours Step (3): after cooling, a permanent 3D polymer object with surface microstructure is obtained. Step (2-3) can be repeated for many cycles and the 2D polymer object can be arbitrarily and cumulatively deformed to get a complex 3D structures. The polymer networks contain reversible exchangeable bonds and bond exchange catalysts in the present invention.

  • Patent number: 9068076
    Abstract: A catalyst masterbatch is disclosed, which when used with a rigid TPU polymer, will cause the rigid TPU to depolymerize during melt processing and repolymerize as the melt is being cooled. This feature is of particular interest in a pultrusion process to create TPU/fiber composites. The catalyst masterbatch contains a relative soft TPU polymer where the catalyst has been swelled or absorbed into the soft TPU polymer. A carrier, such as a plasticizer, can be used to aid the transport of the catalyst into the soft TPU polymer. The catalyst masterbatch is used as an additive to the rigid TPU in a pultrusion process to make the composites. The catalyst masterbatch can also be used in non-fiber reinforced rigid TPU compositions to increase the Mw of melt processed rigid TPU.
