Vinyl polymerization (in bulk and in solution) of a cyclic oligomer of vinyl-methylsilazane (i.e., 1,3,5-trimelhyl-1,3,5-trivinylcyclotrisilazane) was investigated as a method for preparing polymeric precursors to silicon carbide and silicon nitride. After synthesis, the polymers were characterized by size exclusion chromatography and infrared (IR) spectroscopy. Polymers were pyrolyzed under various conditions, and the resulting ceramic products were characterized by IR spectroscopy, X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, elemental analysis, helium pycnometry, and gas adsorption surface area analysis. Potential applications for the polymers are discussed.
