OSTI ID:4180835
Continuing research on the preparation of siliconcontaining polymers that are thermally stable and more rigid at elevated temperatures includes the preparation of both siloxane and nonsiloxane polymers as well as various intermediates and prototype compounds. Attempts to prepare certain bulky monomers, particularly silanes based on s-triazine, were unsuccessful, but siloxanes with bulky pendant groups were prepared. Siloxine polymerization reactions. hydrolysis and ester elimination, were also examined. Non-siloxines that were studied include the systems silicon--oxygen--aluminum, silicon-- oxygen- titanium, silane --pentuerathritol, and silane -- piperazine. Whenever possible, monomers were selected to yield preordered polymers. None of the new systems have properties that equal those of the previously prepared siloxanes. (auth)
