Polyaromatic ether-sulfone-keytones with fluoro-substituted-p-cyclophane units as cross-linking sites

摘要

Polyaromatic ether-sulfone-ketones containing fluoro-substituted-p-cyclophane units were prepared from isophthaloyl chloride, terephthaloyl chloride, diphenyl ether, diphenoxydiphenyl sulfone and a small amount of either 1,1, 2,2, 9,9, 10,10-octafluoro [2,2]-p-cyclophane (type B) or pseudo-p-1,1, 2,2, 9,9, 10,10-octofluoro [2,2]-p-cyclophane bis-acid chloride (type A) by a Friedal-Crafts type polymerization procedure. The p-cyclophane units were incorporated as cross-linking sites.
