Abstract:

Investigation of the synthesis of polyformals from severl nitro- and fluorodiols was continued. A new fluoropolyformal derived from 2,4,4,5,5,6,6-heptafluoro-2-trifluoromethyl-3-oxaheptane-1,7-diol was obtained. Formation of the homopolyformal of 4,4-dinitroheptane-1,7-diol was studied to assess effects of changing reaction parameters on molecular weight. Copolyformal formation was studied for several monomer diol pairs, especially DINOL4,4-dinitroheptane-1,7-diol, and was demonstrated by GPC and H NMR analysis of the polymer products. Effects of varying reaction parameters and monomer ratios were investigated qualitatively. The synthesis of the trifluoromethyl stabilized ring system of bicyclo-HMX 2,4,5,8-tetraza-bicyclooctane was investigated and the di-, tri-, and tetranitro derivatives were prepared and characterized. The chemistry of the 2,6-diazabicyclooctane ring system was studied toward the synthesis of tetra- and hexa-substituted nitro derivatives. Several dinitro derivatives were prepared. A new reduction of nitroamides to nitramino alcohols was discovered. Author
