Abstract

A variety of perfluorocycloalkenyl (PFCA) aryl ether monomers and polymers with enchained triarylamine units were successfully synthesized, characterized and reported here. These polymers are highly thermally stable and show variable thermal properties. Successful conversion of the newly synthesized TAA enchained perfluorocyclopentenyl (PFCP) aryl ether polymers via formylation and EAS demonstrates the synthetic versatility of TAA moiety and provides an excellent option for application specific post polymerization reactions. The cross-linking behavior of PFCP aryl ether polymers was studied under different reaction conditions. The combination of processability, thermal stabilities, and tailorability makes these polymers suitable for a wide variety of applications including electro-optics, proton exchange membranes and super-hydrophobic applications.

Highlights

The serendipitous discovery of poly(tetrafluoroethylene) by Roy Plunkett caught the global attention and led to tremendous improvement in fluoropolymer field [1, 2]
PFCP aryl ether polymers and PFCH aryl ether polymers are synthesized via step-growth polymerization of commercially available bisphenols with octafluorocyclopentene (OFCP) and decafluorocyclohexene (DFCH), respectively (Scheme 2) [27, 28]
The bisphenols are mixed with perfluorocycloalkene (PFCA) monomers in a stoichiometric ratio of 1:1 and heated at 80 °C in the presence of a base, triethylamine
