Abstract

The kinetics of the radiation telomerization of tetrafluoroethylene in 1,2-dibromotetrafluoroethane has been studied. It has been shown that the process occurs very efficiently in the perfluorinated solvent; small doses of γ-radiation (~2 kGy) are required for the complete conversion of the monomer. Telomers with a chain length of 120–360 tetrafluoroethylene units and high thermal stability are formed in the reaction. The structure and properties of the telomers have been studied by IR spectroscopy, thermogravimetry, and elemental analysis.
