There are two methods for introducing functional groups to poly(arylene ether)s, PAEs, in particular poly(arylene ether ketone)s, which are typically prepared via nucleophilic aromatic substitution, NAS. The first method involves the synthesis of functionalized monomers “pre” to the polymerization process. The second method installs the functional groups “post” to the formation of the polymer. It is of interest to design a single monomer that allows either the preparation of functional monomers in situ, followed by subsequent polymerization or preparation of the polymer followed by modification. This presentation describes our efforts to utilize reactivity differences in 3,5,4’-trifluorobenzophenone (1), to prepare functional poly(arylene ether ketone)s via a one-pot procedure. Kinetic studies afforded the activation energies for the three different fluoride reactive sites. The kinetic parameters were then applied to the polymerization of 1, acting as a B2-type monomer, with Bisphenol-A to provide a polymer carrying the third fluorine site for “post” modification.
