摘要：
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 °C) is related to the transition from regular structure to irregular structure and the latter (T-p > 500 degreesC) is associated with the organic-inorgnic transition.
