Abstract: Four organosilicate polymers synthesized by addition of vinyl- and H-substituted double four-ring silicic acid derivatives were characterized using DSC and simultaneous TG-DTA measurements. Thermooxidative decomposition proceeds in several steps. Oxidation of (Si-H9 groups, oxidation of (Si-Ch2-CH2-Si) bridges, and oxidation of (Si-CH3) groups, with formation of new (Si-O-si) bonds. 29Si-NMR-spectroscopic emeasurements confirm this interpretation. Thermoanalytical methods of investigation proved useful to characterize these organosilicate polymers.
