  • DYNAMICALLY CROSSLINKABLE POLYMERIC COMPOSITIONS, ARTICLES, AND METHODS THEREOF
    Publication number: 20230078331
    Abstract: A polymeric composition may include a thermoplastic polymer including: at least one monomer selected from the group consisting of vinyl esters, C2-C12 olefins, and combinations thereof; and a dynamic crosslinking group; and a crosslinking agent to dynamically crosslink the thermoplastic polymer by ionic bonds or metal-ligand interaction.
    Type: Application

  • RECYCLED POLYMER COMPOSITIONS AND METHODS THEREOF
    Publication number: 20220289916
    Abstract: A method may include processing a crosslinked polymer and a catalyst to form a vitrimer during a melt processing operation, the crosslinked polymer comprising at least one monomer selected from a vinyl ester, a C2-C12 olefin, and combinations thereof. A method may include mixing a crosslinked polymer, a catalyst, and a non-crosslinked polymer at a temperature higher than a processing temperature of the non-crosslinked polymer to form a polymer composition; wherein each of the crosslinked polymer and the non-crosslinked polymer comprise at least one monomer selected from a vinyl ester, a C2-C12 olefin, and combinations thereof, and wherein the crosslinked polymer is present in an amount that is at least 15 wt %, relative to the combined total of crosslinked polymer and non-crosslinked polymer.
