Perfluorocyclohexenyl Aryl Ether Polymers via Polycondensation of Decafluorocyclohexene with Bisphenols

A novel class of semifluorinated perfluorocyclohex- enyl (PFCH) aryl ether homo/copolymers was successfully synthesized with high yield through the step-growth polymer- ization of commercially available bisphenols and decafluorocy- clohexene in the presence of a triethylamine base. The synthesized polymers exhibit variable thermal properties depending on the functional spacer group (R). PFCH aryl ether copolymers with random and alternating architectures were also prepared from versatile bis-perfluorocyclohexenyl aryl ether monomers. The PFCH polymers show high thermal

stabilities with a 5% decomposition temperature ranging from 359 to 444 􏰀C in air and nitrogen atmosphere. These semifluori- nated PFCH aromatic ether polymers contain intact enchained PFCH olefin moieties, making further reactions such as cross- linking and application specific functionalization possible.
