Abstract

1365486 Polyarylene sulphones IMPERIAL CHEMICAL INDUSTRIES Ltd 15 June 1972 [5 July 1971] 31414/71 Heading C3R Polyarylene sulphones are obtained by homogeneously oxidizing polyarylene sulphides dissolved in sulphuric acid with solutions of oxidants also dissolved in sulphuric acid. The oxidant may be hydrogen peroxide. In examples polymers having repeating units of formula (obtained by reacting bis-(4-mercaptophenyl)- sulphone, bis - (4 - chlorophenyl) - sulphone and potassium fluoride) are dissolved in sulphuric acid and oxidized with hydrogen peroxide in sulphuric acid.
