AbstractThe thermal conversion of poly(p‐xylyidene tetrahydrothiophenium) chloride into polyparaphenylene vinylene has been studied by Fourier transform infrared spectroscopy (FT‐IR), thermogravimetry, and HCl and tetrahydrothiophene analyses, in the temperature range 20–250°C. Using this system, almost complete elimination can be obtained after only 1 hr heating at 180°C. A side reaction, with the transient formation of C–Cl bond is observed during the heat treatment. After doping with oleum, a stable conductivity is obtained that is not very‐sensitive to the elimination
