• Vitrimers are a new class of polymers that sit between thermoplastics and thermosets.
  • They are covalent adaptable networks (CANs): cross-linked like thermosets, but with dynamic covalent bonds that can break and reform when heated.
  • This gives them:
    • Thermoset-like strength and chemical resistance
    • thermoplastics-like reprocessability Think of them as “plastic glass” (hence the name — from vitrus, glass).
