Novel Poly(keto ether sulfone) as a supporting layer of thin film nanocomposite Membranes

In this article, a new diol was synthesized via aromatic nucleophilic substitution reaction between bisphenol AF and ۴,۴'-dichloro benzophenone. The synthesized diol-FAF reacted with commercially available bis-(۴-flurophenyl sulfone) through condensation polymerization in the presence of K۲CO۳, and the novel PSf (poly-FAF) containing ether, carbonyl group, and aromatic rings were obtained. The FT-IR and ۱H-NMR tests confirmed the chemical structure of new diol and related poly(keto ether sulfone). For the evaluation of polymer molecular weight, inherent viscosity of the polymer was measuered.
