Abstract: | Thermal decomposition of silicon-containing chromium and cobalt γ-(alkylthio)(alkoxy)phosphorylthio]acetylacetonates in air was studied by derivatography. Thermal decomposition of the monomeric metal chelates containing triethylsilyl groups starts from the elimination of the substituent at P, followed by oxidation of the γ-thioacetylacetonate group. Thermal oxidation of polyorganylsiloxanes with phosphorus-substituted γ-thioacetylacetonate fragments starts with the oxidation of the γ-thioacetylacetonate groups, followed by oxidation of the alkoxy and vinylthio groups at phosphorus. |
