We reported previously that the mechanical properties of the amorphous etheric poly[bis(methoxyethoxyethoxy)-phosphazene] (MEEP) were significantly improved by in situ polymerization of tetraethoxysilane (TEOS) (4). This work on etheric phosphazene composites was consistent with reports from the research groups of Mark (5) and Wilkes (6), where metal alkoxides were added to poly(dimethylsiloxane) and poly(tetramethylene oxide). We now extend the phosphazene sol-gel composites to include the more reactive metal alkoxides of titanium, zirconium, and aluminum, and we report that when polymerized in situ, each is compatible with the etheric phosphazene polymer. Dynamic mechanical and stress-strain techniques are utilized to evaluate and compare the mechanical properties of the different composites. Thermal and... [Pg.258]
