Poly(ether ether ketone)s (PEEK) have unique thermal stability, solvent resistance and mechanical properties. Since the original synthesis of PEEK, many modifications have been made to enhance their properties. Previously, PEEK monomers having oxyalkylene linkages were synthesized and polymerized in typical AA + BB polymerization reactions using NAS conditions. Two AB versions of these monomers (4-fluorophenyl)(4-(2-(4-hydroxyphenoxy)ethoxy)phenyl)methanone and 4-(2-(4- phenoxyphenoxy)ethoxy)benzoic acid have been synthesized and polymerized by typical NAS (Potassium Carbonate, Toluene, NMP) and Friedel-Crafts (MSA, Phosphorous Pentoxide) procedures, respectively.
