Continuing research on the preparation of siliconcontaining polymers which are thermally stable and more rigid at elevated temperatures is described. In studies of the use of bulky groups, sodium hydroxide treatment of siloxanes containing one bulky group attached to silicon failed to significantly alter the properties of the materials. Also, attempts to synthesize bulky silane monomers based on the s-triazine ring were unsuccessful. When methods other than hydrolysis were examined for the formation of polymers from arylenedisilanes, ester elimination procedures appeared to be satisfactory. However, attempts to obtain the intermediate silanols for use as polymerization intermediates were not successful. Condensation of silanes and pentaerythritol or its derivatives failed to yield structures in yields useful in polymerization reactions. Additional studies of silicon-oxygen-titanium systems are described. (For preceding period see NP-7890.) (auth)
