Poly aryl sulfone

Recendy, Guiver et al. reported a number of derivatives of polysulfone and poly(aryl sulfone).172 188 Polysulfones were activated either on the ortho-sulfone sites or the ortho-ether sites by direct lithiation or bromination-lithiation. The lithiated intermediates were claimed to be quantitatively converted to azides by treatment with tosyl azides. Azides are thermally and photochemically labile groups capable of being transformed readily into a number of other useful derivatives.

The goal of the polymer industry is the design of a low-cost flame retardant polymer that does not require additives yet still has favorable physical and mechanical properties. New flame-resistant engineering plastics that have been commercialized are used in specialty applications. These include poly aryl sulfone and poly-etheretherketone (PEEK). These polymers work as heat-/flame-resistant polymers, but because of their...

Poly(aryl sulfone) n. An aromatic polymer consisting of benzene rings finked by both sulfone (-SO2-) groups and ether oxygen atoms. Poly(aryl sulfones) can be synthesized by solution polymerization in a polar solvent. Several commercial products of this type have been developed as reasonably high temperature resistant engineering plastics.

Polysulfone (PSU) is a family of thermoplastic polymers they are classified as PSU, poly(aryl sulfone), and poly(ether sulfone) (PES) by the polymer backbone structure. They are well known for their toughness and stability at high temperatures (-100°C to 150°C), high oxidative stability, and dimensional stability. Hence, it is easy to get the thin membrane with reproducible properties, which have been widely used in many fields like hemodialysis, wastewater treatment, gas separation, and especially PEM fuel cell applications.
