Poly(aryl ether)s attained commercial success due to their high thermal stability, hydrolytic stability, and compatibility with commodity polymers. However, they also have high melt viscosities and high melt temperatures, which lead to oxidation and gelation during processing. Dakarai K. Brown, Jean‐Marc Cracowski, Scott T. Iacono, Kenneth Christensen, and Dennis W. Smith Jr. prepare a series of new segmented semifluorinated polyaryl ethers containing a biphenyl segmented by semifluorinated oligoethylene units by nucleophilic addition of a commercial oligo(ethylene glycol)s to 4,4′‐bis(4‐trifluorovinyloxy)biphenyl. The cover shows an AFM image of the needle‐like crystalline morphology observed in segmented semifluorinated poly(aryl ether). (DOI: 10.1002/app.41798 )
