Abstract :

Post-polymerization modification (PPM) strategies have been creatively utilized to prepare functional perfluorocyclobutyl (PFCB) aryl ether polymers and partially fluorinated arylene vinylene ether (FAVE) polymers. To apply PPM via ketene chemistry, a new Meldrum�s acid functionalized aromatic trifluorovinyl ether (TFVE) monomer was designed, synthesized, and successfully utilized to prepare Meldrum�s acid-functionalized PFCB aryl ether polymer precursors via traditional thermal cyclopolymerization. Functional PFCB aryl ether polymers can be prepared by heating Meldrum�s acid functionalized polymer precursor with functional nucleophiles at a certain temperature via ketene chemistry, which was demonstrated by the preparation of a Disperse Red 1-functionalized PFCB aryl ether polymer. To apply PPM in FAVE polymers, a novel ester-functionalized FAVE polymer precursor was designed and synthesized, which was used to prepare three reactive FAVE polymers containing carboxylic acid groups, alcohol groups, and acid chloride groups. Post-polymerization modifications of the FAVE polymer�s carboxylic acid groups (via a DCC coupling procedure with the desired alcohol), alcohol groups (via DCC coupling or an acid chloride esterification procedure with the desired carboxylic acid or acid chloride), and acid chloride groups (via an optimized nucleophilic substitution reaction with the desired alcohol or amine) were successfully performed. No degradation of the FAVE polymer matrix occurs after multistep post-polymerization modification reactions. A variety of functional fluorinated polymers can be prepared via the PPM strategies we developed.
