Abstract

Abstract: The novel and soluble poly(ether ether ketone)(PEEK) containing fluorin structure(6F-PEEK) was prepared by nucleophilic reaction of 4,4’-difluorobenzophenone, bisphenol A and hexafluobisphenol A in the presence of anhydrous K₂CO₃ with tetramethylene sulfone as the solvents. The molecular weight of the polymer was determined by GPC. The structure of the polymer was characterized by FTIR, ¹H NMR and ¹⁹F NMR spectroscopies. The glass transition temperature and the temperature for 5% mass loss of 6F-PEEK were 153 and 493 ℃, respectively. The polymer exhibits an excellent thermal stability, mechanical property and solubility. The rate of elongation at break, tensile strength and tensile modulus of 6F-PEEK were 55.2%, 66 MPa, and 2.13 GPa, respectively.

Key words: Poly(ether ether ketone), Hexafluobisphenol A, Fluorinated polymer, Soluble PEEK
