摘要
A kind of highly fluorinated bisphenol monomer was synthesized. It was characterized by FTIR, 1H NMR and MS. 6F PEEK and 6F PEEKK were prepared via aromatic nucleophilic substitution, based on [3,5 di(trifluoromethyl)] phenylhydroquinone and difluoro monomers. The T gs of 6F PEEK and 6F PEEKK are 423 and 436 K, respectively. The 6F polymers exhibit a high thermal stability and good solubility. The flexible, creasable and transparent thin films were easily obtained by compression moulding and solution casting.
