A type of novel crosslinkable fluorinated poly(aryl ether ketone) containing pendent phenylethynyl moieties (PEP-3F-PEEKn) have been synthesized by copolycondensation reaction of difluoro-monomer with potassium salt of 4-phenylethynylphenyl hydroquinone (PEP-PH) and (3-trifluoromethyl) phenyl hydroquinone 3F-PH). The resulting polymers could be thermally crosslinked at 370 degrees C. The cured polymers showed good solvent resistance, high thermal stability up to 500 degrees C under nitrogen. They had small light absorption at the telecommunication wavelengths of 1.3 and 1.55 mu m. The refractive index of the cured films was in the range of 1.6154-1.6274 at 1.55 mu m wavelength.
