To investigate the effect of cross‐linking on partially fluorinated anion exchange membranes tethered with trimethylpropyl side chains (QPAF‐C3), styrene‐based cross‐linker is introduced into precursor copolymers and then cross‐linked via free radical reaction. The one‐pot quaternization reactions are successful as confirmed through nuclear magnetic resonance spectra. By solution casting, resulting polymers provide flexible (xQPAF‐C3‐VB) 9.1–36.0% degree cross‐linking. results in smaller...
