Oxygen–Nitrogen Switchable Copolymers of 2,2,2‐Trifluoroethyl Methacrylate and N,N‐Dimethylaminoethyl Methacrylate

In this work, a novel class of O2 /N2 switchable polymers is reported, which is prepared by atom transfer radical copolymerization (ATRcoP) of commercially available 2,2,2-trifluoroethyl methacrylate (FMA) and N,N-dimethylaminoethyl methacrylate (DMA). The copolymer is random and contains 10 FMA units and 85 DMA units. Its aqueous solution becomes transparent with O2 bubbling and turns to turbid with N2 purging. This O2 /N2 -responsive …
