Poly(ether ether ketone)s (PEEK) polymers are known for their unique properties including excellent thermal stability, solvent resistance and mechanical properties. Since their discovery, various alterations have been done to enhance their properties one of which has been the inclusion of alkylenedioxy linkages with all para linkages. A series of meta substituted PEEK monomers have been synthesized via a three-step process involving alkylenedioxy dibenzaldyde synthesis, Grignard reaction to aid the addition of fluorophenyl groups and subsequent oxidation to form a fluorophenyl ketone. Polymerization occurred in an A2+B2 fashion with bisphenol-A under NAS conditions (NMP, toluene, potassium carbonate). Characterization of the meta substituted polymers will be presented in comparison to the previously reported para systems.
