Changes of composition and structure of various samples of polymethylsilsesquioxane (PMSQ) pyrolysed at different temperature under flowing nitrogen were investigated by means of FT-IR and X-ray photoelectron spectroscopy.Two temperature domains correspond to important changes in the chemical composition of PMSQ.The former (T^p < 500℃) is related to the transition from regular structure to irregular structure and the latter (T^p > 500℃) is associated with the organic-inorgnic transition.
