Аннотация
The radiation-induced telomerization of tetrafluoroethylene in pentafluorochlorobenzene, pentafluorobromobenzene, and hexafluorobenzene has been studied. It has been shown that the process efficiency and the chain length of the resulting telomers depends on the binding energy of the substituent in the fluorinated benzene rings. An analysis of the IR spectra showed that changes in the molecular structure of telomers occurred under the influence of gamma radiation; these changes were expressed in the detachment of terminal benzene rings and the formation of terminal carboxyl groups. In addition, polymer chain degradation leading to the formation of telomers with a shorter chain length was observed. The hydrophobic properties of the samples of all irradiated telomers were preserved.
