An improved procedure for the preparation of trifluorovinylsilanes was established which involved addition of butyllithium to a mixture of chlorosilanes and commercially readily available chlorotrifluoroethylene at -78 to -130 deg C, and the resulting monomer was polymerized with a catalyst such as CsF or (R2N)3S(1+)*F2SiMe3(1-) to give black metallic polymer which showed conductivity of 1E-9 to 1E-10 Ω^-1cm^-1.
