Abstract
1,3‐Bis(p‐phenoxybenzenesulfonyl)benzene (I), 4,4′‐diphenoxy‐diphenyl sulfone (II), diphenyl ether, and 3,9‐bis(p‐phenoxybenzoyl) [2.2]‐p‐cyclophane were polymerized with isophthaloyl chloride in Friedel‐Crafts type polymerization. The polymers obtained, containing 6–8 wt.‐% of p‐cyclophane units were moderately soluble in HMPA and sulfuric acid with inherent viscosities, between 0.5 and 1.0. The polymers cured at 375°C for 3 days showed little penetration up to 400°C in the Vicat softening curves. Strong molding disks and laminates on glass fiber can be made with excellent thermal stability.Keywords
