Abstract: Novel cyclic aryl ether sulfone oligomers have been synthesized in high yield based on bisphenol Aand 4-fluoro-3-nitrophenyl sulfone firstly through interfacial polycondensation reaction under a pseudo-high-dilution condition. Detailed structural characterization of the oligomers by MS, GPC, NMRand IRanalyses confirmed the cyclic nature.

Key words: Interfacial polycondensation, Cyclic aryl ether sulfone, Bisphenol A
