【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.更多还原
