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-octpfluoro 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. Author
