- 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).
