ABSTRACT:
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 Friedel-Crafts type polymerization procedure. The p-cyclophane units were incorporated as cross-linking sites.
