Notizen:
The synthesis of poly(ether sulphone) using the ‘carbonate’ route based on the reaction of 4,4′-dihydroxydiphenylsulphone, 4,4-dichlorodiphenylsulphone and potassium carbonate dispersed in diphenylsulphone has been studied by 13C CPMAS NMR spectroscopy. In the initial reaction the half potassium salt of 4,4′-dihydroxydiphenylsulphone is formed. No evidence for a stable full salt was found at any time during the polymerisation cycle and no appreciable oligomer formation took place before the polymerisation itself took place.
