Notes:
The condensation polymerizations of bis(4-flurophenyl) sulfone with the bistrimethylsilyl derivates of bisphenol-A, 4,4′-dihydroxydiphenyl sulfone, 1,5′-dihydroxynaphthalene, 3-hydroxybenzoic acid, and 4-hydroxybenzoic acid were investigated. These polycondensations were only successful when potassium or cesium fluoride was used as catalyst. The yields were in the range of 91-98% and the number molecular weights in the range of 2,500-17,500 depending on the reaction conditions. Viscosity and GPC measurements were conducted and glass transitions were determined. Crystallization was never observed.
