Vinyl ethers are twelve electron‑rich reactive monomers commercially produced via the Reppe process. Structurally characterized by an ether‑oxygen linked to an active vinyl group, they enable ultra‑fast cationic homopolymerization/photocationic curing, and highly regular alternating copolymerization with electron‑deficient monomers like maleic anhydride or chlorotrifluoroethylene.
