Abstract: A kind of polyetheretherketone ketone has been prepared by copolyeondensation of 4,4′-diphenol, 1,3-bis (4-fluorobenzoyl) benzene and 1,4-bis (4-fluorobenzoyl) benzene with alkali metal carbonates at 310~320℃ using diphenylsulphone as solvent. The copolymer has Tg=169℃,Tm=339℃, 2.5% weight loss at 555℃;tensile strength 68.5MPa and tensile modulus 0.915GPa.

Key words: polyetheretherketoneketone, bis fluorobenzoyl benzene, diphenol, heat resistant polymer, synthesis
