摘要

Cyclic oligomers of phenolphthalein polyarylene ether sulfone(ketone) were preparedthrough cyclo-depolymerisation of corresponding polymers using CsF as the catalyst in dipolaraprotic solvent DMAc and DMF, and a family of macrocycles containing from dimer up to at leastheptamer were confirmed by GPC, HPLC and MALDI-TOF-MS. The yields of cyclics get ashigh as 86.3% and 87.9% respectively.
