Аннотация:The kinetics of the radiation telomerization of tetrafluoroethylene in 1,2-dibromotetrafluoroet-hane 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.
