Abstract
Products of the thermal condensation of polymetalloorganosiloxanes in an inert atmosphere are hydrocarbons formed by detachment of organic groups from the silicon atom. Some of the organic groups remain in the pyrolyzed residue in the form of polyaromatic nuclei and silphenylene fragments (for polymetallophenyl-siloxanes). The pyrolysis residue also contains reduced forms of the metal, carbides and carbide-suicides of the metal, and silicon dioxide. Radical process schemes are proposed for an explanation of the formation of hydrocarbons, reduced forms of the metal, and silicon dioxide in the course of thermal condensation of polymetalloorganosiloxanes.
