Novel hybrid organic-inorganic systems (HOIS) have been prepared by the sol-gel method from precursors containing silica and crown ethers fragments. Investigations of HOIS by IR-spectroscopy and thermogravimetric analysis have shown that the structure and properties of HOIS are determined by the nature of physical interactions of interstitial fragments. WAXS investigations of HOIS have been carried out. The correlation between the HOIS composition and their resistance to thermooxidative degradation opens a wide prospect for the creation of thermostable materials.
