This paper first introduces the research progress in recent years, poly (aryl ether ketone), poly aryl ether sulfone thesis consists of six parts: 1, thionyl role as the starting material, 9,9 - dichloro-xanthone xanthene ketone t intermediates, in turn respectively with phenol, o-methyl phenol, 2,6 - dimethyl phenol substitution reaction, prepared containing the xanthene structure bisphenol monomer - 9,9 - two (4 - hydroxyphenyl) xanthones-t (BHPX), 9,9 - bis (3 - methyl-4 - hydroxyphenyl) xanthene, 9,9 - bis (3,5 - dimethyl-4 - hydroxyphenyl) xanthene, produced The rates were 85%, 78%, 75%. 2, under nitrogen in K2CO3 presence of sulfolane as a solvent, 9,9 - bis (4 - hydroxyphenyl) xanthene (BHPX) and 4,4 '- difluoro-benzophenone and bisphenol A terpolymer; 9,9 - bis (3 - methyl - 4 - hydroxyphenyl) xanthene and 4,4 '- difluoro-benzophenone and bisphenol A terpolymer; 9,9 - bis (3,5 - methyl-4 - hydroxyphenyl) xanthene and 4,4 '- difluoro-benzophenone and bisphenol A terpolymer of three series of new main chain structure containing xanthene poly (aryl ether ketone) polymer, class has polyaryletherketone the higher heat resistance. Having a Tg range of between 180 to 257 ° C, the logarithmic ratio of the resulting polymer viscosity number of 0.470 to 1.645dL / g, a tensile strength of of of 48 ~~ 75 MPa, tensile modulus of 1.54 ~~ 2.70 GPa, the elongation at break long rate of 7 to 13%, soluble in NMP, DMF, DMAc, etc. strongly polar aprotic organic solvents. 3, using 9,9 - bis (3 - methyl-4 - hydroxyphenyl) xanthene, 9,9 - bis (3,5 - dimethyl-4 - hydroxyphenyl) xanthene and multiple pairs fluoromonomer under nitrogen in K2CO3 presence of sulfolane as the solvent, the high temperature solution polycondensation into a series of poly (aryl ether ketone). These dual fluoromonomer include 4,4 '- difluoro-benzophenone, 1,3 - bis (4 - fluoro-benzoyl) benzene, 4,4' - two (4 - fluoro-benzoyl) biphenyl, 4,4 '- bis (4 - fluoro-benzoyl) diphenyl ether, in the polymerization reaction, the sulfolane as solvent. 0.474 to 1.327dL / g, the viscosity of the resulting polymer capable of dissolving in methylene chloride, chloroform, tetrahydrofuran, pyridine, DMF, and the DMAC, 1,2 - dichloroethane, and NMP. Tg between 194 ℃ and 276 ℃ between 5% weight loss temperature (Td) in a nitrogen atmosphere at 400 ℃. The tensile strength of the film is 58 ~ 63 MPa, tensile modulus of 2.02 ~ 2.27 GPa, the elongation at break was 7% to 9%. 4, using the method of solution polymerization, under nitrogen, 9,9 - bis (4 - hydroxyphenyl) xanthene and 4,4 '- chloro diphenyl sulfone and hydroquinone terpolymer; 9 - bis (4 - hydroxyphenyl) xanthene, and 4,4 '- difluoro-benzophenone and bisphenol S terpolymer, a series of new main chain structure containing xanthene polyarylene ether sulfone polymerization thereof. The resulting viscosity of the polymer in the 0.50 ~ 1.53 dL / g, can be dissolved in an aprotic organic solvent of strong polarity such as DMF, DMAC and NMP. Tg range between 207 ℃ and 259 ℃, the 5% thermal weight loss temperature (Td) in a nitrogen atmosphere at between 458 ℃ and 520 ℃. The tensile strength of the film is 41 ~ 53 MPa, tensile modulus of 2.29 to 2.46 GPa, the breaking elongation of 7 to 9%.
