Trifluorovinyl methyl, ethyl, isopropyl and tert-butyl ethers have been prepared. These trifluorovinyl ethers show C=C absorption at such a short wavelength as 5.46∼5.50μ. The methyl and ethyl ethers can be polymerized by free-radical initiators. Halogen addition products of trifluorovinyl- and 1, 2-difluoro-2-chlorovinyl ethers have also been prepared. With α-halo or vinyl ethers, the reactions that
