English
A KIND OF POLYETHERETHERKETONE KETONE CONTAINING DIPHENYL GROUP
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.
