详细

A spectral study of radiation-synthesized telomers of tetrafluoroethylene with different end groups has been carried out by Raman spectroscopy for the first time. The effect of gamma radiation on the molecular structure of telomeres and hydrophobic coatings of aluminoborosilicate glass fabric based on them was studied. Changes in the molecular and morphological structure of telomeres are observed under the action of gamma radiation.
