“…Functionalized fluoropolymers would be of interest because they would combine the aforementioned merits of fluorinated materials for specific applications [4]. Such tailored fluoropolymers, specifically PFCB aryl ethers, have been involved in various applications including thermally crosslinkable additives [5], proton exchange members (PEMs) for fuel cells [6,7], chemical sensors [8,9], polymer light emitting diodes (PLEDs) [10], gas separation membranes [11], and electro-optical (EO) materials [12,13].…”

Polyethylene glycol (PEG) end‐capped trifluorovinyl ether (TFVE) telechelomer was synthesized in one step via esterification of 4‐(trifluorovinyloxy) benzoic acid. The new telechelomer was characterized by attenuated total reflectance Fourier transform infrared (ATR‐FTIR), elemental analysis, and by 19F and 1H nuclear magnetic resonance (NMR) spectroscopy. The telechelomer and 4,4′‐bis(4‐trifluorovinyloxy)biphenyl (BPVE) were thermally copolymerized via step‐growth [2 + 2] cycloaddition at 160°C. The polymerization afforded PEG enchained biphenyl perfluorocyclobutyl (BP‐PFCB) copolymers that are solution processable and film forming. These copolymers were characterized by ATR‐FTIR, 19F NMR, and 1H NMR. Gel permeation chromatography (GPC) gave number‐average molecular weight (Mn) ranging 11,000 to 12,000. Compatibilization of PEG and a commercial polymer BP‐PFCB was achieved utilizing the new PEG BP‐PFCB copolymer, 3‐co2‐4. It was found that 5 wt% of 3‐co2‐4 was ideal to reduce interfacial tension by scanning electron microscope (SEM). In addition, phase homogeneity was studied by differential scanning calorimetry (DSC). Copyright © 2016 John Wiley & Sons, Ltd.

“…Perfluorocyclobutyl (PFCB) aryl ether polymers and fluorinated arylene vinylene ether (FAVE) polymers are two such classes, synthesized via step growth polymerization of aromatic trifluorovinyl ether (TFVE) monomers (Scheme 1). [20][21][22][23][24] The aromatic backbones in these semifluorinated polymers not only address the performance issue, but also provide a means for facile modification to achieve modular utility.…”

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.
