Applications:
Polysulfones are commonly prepared from a bis-(p-halophenyl) sulfone and
a dihydric compound, such as bisphenol A, in a dipolar aprotic solvent such
as Dimethyl Sulfoxide.
While many solvents may compete in the large category of polymer synthesis, DMSO comes into its own regarding high temperature engineering resins such as polysulfones (PES, PS), polyaryletherketones (PEK, PEEK, PEKK).
