Synthesis and characterization of processable aromatic poly(azomethine)s with ether linkages

<jats:title>Abstract</jats:title><jats:p>High‐molecular‐weight polyketanils with flexible ether linkages were prepared by the reactions of <jats:italic>N</jats:italic>,<jats:italic>N</jats:italic>′‐bis[α(4‐fluorophenyl)benzylidene]‐1,4‐benzenediamine with phenoxides derived from several less acidic diphenols. Molecular sieves medicated reactions of 1,4‐benzenediamine with two equivalents of 4‐flurobenzophenone afforded the desired monomer in good yield. Formation of successive ether linkages via nucleophilic aromatic substitution reactions constituted the polymerforming step. The high‐molecular‐weight polymers form tough films upon compression molding, exhibit relatively high glass transition temperatures and good thermal stability.</jats:p>
