Abstract

Novel cross-linkable, highly fluorinated poly(arylene ether ketone/sulfone)s have been prepared by copolycondensation reactions of a perfluorinated aromatic ketone or sulfone with 4,4'-(hexafluoroisopropylidene)diphenol (6F-BPA)/4,4'-isopropylidene bis(2,6-dibromophenol) (4Br-BPA) and a tetrafluorostyrol-containing bisphenol, at low temperature in the presence of calcium hydride and cesium fluoride. Property investigations have shown that these polymers can be easily processed into thin films, have good thermal stability, and exhibit low optical loss at 1550 nm (0.4 – 0.5 dB/cm). The refractive index can be tailored over a range of 1.50 to 1.57, allowing the polymers to be used as both core and cladding materials in optical waveguiding applications.
