“…Thermally stable polymers are critical for many applications. Numerous industries are pushing the limits of current organic backbone polymers. − One possible solution is to use hybrid materials, with organic–inorganic bonds in the polymer backbone, for enhanced thermal stability. − Siloxanes are one such family of materials; however, until now their ultimate thermal stabilities have been limited by degradative depolymerization which occurs at lower temperatures than anticipated based on Si–O bond strengths …”
