| Popis: | The thermal oxidative degradation of a polymer composite material based on polytetrafluoroethylene and oxyfluoride glass of composition 18BaF2–31SiO2–19B2O3–24BaO–8TiO2 under dynamic conditions has been studied. It is noted that the decomposition process takes place in several stages. The gaseous products of thermal oxidative destruction of the composite material were studied by mass spectrometry. The results of thermogravimetry and differential scanning calorimetry showed the stabilizing effect of oxyfluoride glass on the stability of polytetrafluoroethylene at elevated temperatures. |
