Low-temperature post-irradiation telomerization of tetrafluoroethylene in alcohols

Kinetic calorimetry was used to study the kinetics of low-temperature post-radiation telomerization of tetrafluoroethylene in ethanol and hexafluoroisopropanol. The temperature range in which the reaction occurs and its efficiency depend on the phase state of the reaction mixture at low-temperatures and on the chemical nature of the solvent. The nature of active centers initiating the telomerization process of tetrafluoroethylene in hexafluoroisopropanol and their accumulation kinetics were examined by EPR spectroscopy. The molecular structure and properties of the resulting telomers were examined by IR spectroscopy and thermogravimetric analysis.
