STUDY OF RADIOLYSIS PRODUCTS OF TELOMERES PRODUCED BY TETRAFLUOROETHYLENE POLYMERIZATION IN CARBON TETRACHLORIDE

In this work, tetrafluoroethylene telomers were synthesized in carbon tetrachloride. The resulting telomers were then irradiated in air with ⁶⁰Co γ-rays at doses in the range of 18–1020 kGy. When studying the IR spectra of the irradiation products, it was found that the intensity of the absorption band (AB) at 850 cm^–1, which can be associated with the –CCl₃ terminal groups, decreases with increasing irradiation dose. At the same time, a new AB appears in the IR spectrum at ~1775 cm^–1, caused by the carboxyl group, the intensity of which increases with increasing irradiation dose. Studying the dependence of the intensity of the noted AB on the dose allowed us to conclude that the removal or transformation of the terminal –CCl₃ groups and the formation of –COOH groups are independent processes.
