  • Publication number: 20240286178
    Abstract: Systems, methods, and compositions relating to pretreatment and enzymatic degradation of polymeric materials comprising one or more crystallizable polymers or copolymers are generally described. Certain aspects are directed to methods comprising reacting a polymeric material comprising a crystallizable polymer or copolymer with a reactive agent to produce a pretreated polymeric material and exposing the pretreated polymeric material to a polymer-degrading enzyme. In some embodiments, the reactive agent induces chain extension, branching, and/or cross-linking of the crystallizable polymer or copolymer. In some embodiments, the reactive agent induces chain scissions followed by chain extension, branching, and/or cross-linking of the crystallizable polymer or copolymer.

  • Patent number: 10377867
    Abstract: Polymer network composition having a semi-crystalline covalently crosslinked polymer network including exchangeable covalent bonds and crosslinking bonds and at least an exchange reaction catalyst, wherein the number of crosslinking bonds is sufficient for the polymer network to be beyond the gel point and the number of exchangeable bonds is sufficient for the network to relax stresses and/or flow when conditioned at an appropriate temperature. Such compositions are characterized by the fact that the network is able to reorganize by exchange reactions that allow it to relax stresses and/or flow while maintaining network connectivity.

  • Patent number: 10329414
    Abstract: The object of the invention is polymer compositions comprising cross-linked polymer comprising boronic ester functions enabling exchange reactions, as well as free monofunctional boronic esters. The compositions are obtained from the modification of a polymer by a functionalized boronic ester additive. This polymer can be pre-functionalized boronic ester or functionalized on addition of the said additive. In particular, the invention relates to a process enabling the behavior of a polymer to be modified by addition of a functional additive, enabling a cross-linked network containing exchangeable boronic ester links to be formed.
