Synthesis and Characterization of Novel Fluorine-containing Poly(aryl ether ketone)s

Abstract

Abstract: 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-PEEKKare 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.

Key words: Poly(aryl ether ketone)s, Solubility, Fluorine-containing polymers
