Did you know?
The simplest polysulfone poly(phenylene sulfone), known as early as 1960, is produced in a Friedel-Crafts reaction from benzenesulfonyl chloride: n C6H5SO2Cl → (C6H4SO2)n + n HCl With a melting point over 500 °C, the product is difficult to process. It exhibits attractive heat resistance, but its mechanical properties are rather poor.

WebBis (4-chlorophenyl) sulfone was purified by recrystallization from benzene—m.p. 145°-147°C (4). Extremely low yields were obtained by this process. By contrast, yields in excess of 90% have been reported in processes that involve the reaction of chlorobenzene with sulfur trioxide and dimethyl or diethyl sulfate (5, 6).
