  • METHODS FOR INCORPORATING DYNAMIC BONDS INTO EXISTING POLYMERS
    Publication number: 20250034341
    Abstract: Synthetic methods for forming a crosslinked polymer network with dynamic bonds within its crosslinks from a pre-existing unsaturated organic polymer are provided. The dynamic bonds enable the resulting crosslinked polymer network to be chemically or mechanically recycled or otherwise reprocessed. Also provided are crosslinked polymer networks made using the synthetic methods and methods for reprocessing the crosslinked polymer networks using thiol exchange reactions.
    Type: Application

  • Photocontrolled dynamic covalent linkers for polymer networks
    Patent number: 11820870
    Abstract: Reversibly crosslinkable polymeric networks, including reversibly crosslinkable hydrogel networks are provided. Also provided are methods of making the polymeric networks and methods of using the hydrogel networks in tissue engineering applications. The reversibly crosslinkable polymeric networks are composed of polymer chains that are covalently crosslinked by azobenzene boronic ester bonds that can be reversibly formed and broken by exposing the polymeric networks to different wavelengths of light.
    Type: Grant
