Abstract

Poly(ether ketone)s containing 1,3‐dicyclohexyl‐1‐methyl‐3‐phenylindan groups in the main chain were prepared from different bisphenols and a bisfluoride monomer which contains the indan group. The bisfluoride monomer was synthesized in a three‐step process, starting from cyclohexyl phenyl ketone. All polymers are soluble in tetrahydrofuran, chloroform and N,N‐dimethylpropyleneurea. No melt transitions were detected by differential scanning calorimetry. Glass transition temperatures are relatively high (218°C to 255°C). In gel‐permeation chromatography with polystyrene calibration, 8400 < M̄~n~ < 17900 and 34500 < M̄~w~ < 76600 were found. The thermooxidative stability of these polymers is fairly low with decomposition starting at 400°C in air. This was attributed to the methine group of the cyclohexyl ring since the major decomposition products proved to be cyclohexane and cyclohexene.
