AbstractThree amorphous aromatic polyether sulfone(ketone)s with different structures underwent a cyclo-depolymerization reaction using CsF as the catalyst in dipolar aprotic solvents such as DMAc and DMF to afford corresponding cyclic oligomer products. The results were confirmed by GPC, HPLC and MALDI-TOF-MS. The yields of phenolphthalein polyether sulfane (PES-C) and phenolphthalein polyether ketone (PEK-C) cyclics reach as high as 86.3% and 87.9% respectively. Relative factors that influence the yields of cyclics were discussed. High molecular weight linear products were regenerated after the ring-opening polymerization of the cyclo-products using potassium phenoxide as initiator.
