The synthesis of a series of novel semi-fluorinated graft copolymers bearing perfluorocyclobutyl (PFCB) aryl ether-based backbone and polystyrene side chains is described. This work initially focused on the synthesis of a trifluorovinyl ether (TFVE) monomer containing a bromine atom, which could be employed as an initiating site for atom transfer radical polymerization (ATRP). Thermal cyclopolymerization of this TFVE monomer provided a macromolecular initiator followed by subsequent initiating ATRP of styrene to afford the desired PFCB aryl ether-based graft copolymers.
