| Popis: | Nuclear magnetic resonance (NMR) of and is used in this study to monitor the structural evolution with temperature of the inorganic polymeric glass whose vitreous transition temperature, determined by differential scanning calorimetry, is K. A local motion, essentially around the fluorine atoms, particularly on one kind of the fluorine atoms, is observed below . Above this glass decomposes into a two-phase material - glass + gas; the origin of the formation of the gas is explained and the proportion gas/solid is followed when the temperature is varied. |
