preparation example Construction

[0044] The preparation method of the polyarylsulfone polymer containing the reduced phenazine structure of the present invention comprises the following steps:

[0045]Put the difluoro monomer containing sulfone group, bisphenol A, reduced phenazine, catalyst potassium carbonate, solvent sulfolane or N-methylpyrrolidone, and water-carrying agent toluene into a three-stage tank equipped with nitrogen port, oil-water separator, and mechanical stirring. In a nitrogen atmosphere, stir and heat to 140-150°C to reflux the toluene for 3 hours, then use an oil-water separator to release toluene and water after fully carrying water, then raise the temperature to 200-220°C and stir for 3-8 hours to obtain To reduce the phenazine polyarylsulfone polymer, the reaction formula is (i):

[0046]

[0047] In the formula, n is the degree of polymerization, 0<m≤1 represents the copolymerization ratio, and Ar is one of the formulas (a) to (d):
