Abstract:

Several samples of a silicon-nitrogen elastomer were characterized. Characterization included structure analysis, solubility, solution viscosity, thermal properties, and molecular weight. Several samples of the perfluoroalkyl bibenzoxazole polymers were examined. Considerable effort was directed toward determination of the molecular weight of both perfluorosebacate and perfluoroalkyl ether-linked polymers. In addition, solubility, thermal stability and subambient DTA of the perfluoroalkyl ether- linked polymers elastomers were investigated. Samples of the aromatic heterocyclic-ladder type were also studied, as was the product obtained by heating 1- carboxy-2-chloroferrocene. Finally, several samples of polyspirocyclobutane polymers were characterized. Characterization include structural analysis, solubility, and thermal properties. The approach to solvent search was examined in the light of recent literature. It was concluded that division of the solubility parameter into electrostatic and covalent contributions would describe solvent properties pertinent to solution formation. This was supported by examination of solubility data for several polymers.
