Synthesis of novel macromonomers with polyether possessing fluorine and their polymerization

Novel styrene-type and methacrylate (MA)-type macromonomers with polyether(poly(oxytetramethylene)) possessing a fluorobutyl terminal group were synthesized by the reaction between 4-aminostyrene or 2-hydroxyethyl methacrylate and polyether with a fluoroformyl group at one chain end (prepolymer), which was prepared by the ring-opening polymerization of THF with hexafluoropropylene oxide (HFPO) as an initiator. Macromonomers were easily prepared by mixing a solution containing the prepolymer with 4-aminostyrene or 2-hydroxyethyl methacrylate for several minutes at room temperature. The obtained macromonomers can polymerize with either radical or anionic initiator to afford polystyrene or poly(MA) with polyether grafted segment in each monomer unit.
