DOI: 10.1002/marc.201800889
Abstract: Epoxy vitrimers prepared from anhydride-cured epoxies exhibit, repairable and reprocessable properties; however, they generally rely on a large amount of catalyst for accelerating the dynamic transesterification (DTER). If the catalyst loading is not enough, the… read more here.

DOI: 10.1016/j.mtcomm.2021.102814
Abstract: Abstract Vitrimers have covalent crosslink structures as normal thermoset polymers, but they possess unique properties of being able to go through plastic deformation due to their crosslinks being dynamically exchangeable above a particular temperature. This… read more here.

DOI: 10.3390/polym14153180
Abstract: Traditional crosslinked aero grade epoxy resins have excellent thermal-mechanical properties and solvent resistance, but they cannot be remolded, recycled, or repaired. Vitrimers can be topologically rearranged via an associative exchange mechanism, endowing them with thermoplasticity.… read more here.
