Embodiment 1

[0032] In the three-neck flask equipped with a stirrer, one side port is connected to a tee to place a thermometer and a high-purity nitrogen gas inlet, and the other side port is connected to a spherical condenser tube for exhaust. Place the three-neck flask in the electric heating mantle, add 174.54g (0.8mol) of 4,4'difluorobenzophenone, 96.89g (0.88mol) of hydroquinone and 800g (3.67mol) of diphenyl sulfone, Start the stirring device, and feed high-purity nitrogen with a flow rate of 60 ml / min at room temperature. Then, the reactant was heated to 150° C. at a heating rate of 2° C. / min, and 84.79 g (0.80 mol) of sodium carbonate was added immediately thereafter. The reaction temperature was raised to 300°C at a ramp rate of 2°C / min. The temperature of 300°C was maintained until an increase in the viscosity of the reaction mixture to the desired value of 410 Pa·s was observed. Immediately add 1.75 g (0.008 mol) of 4,4'-difluorobenzophenone again for capping to control the m...

Embodiment 2

[0036] Add 152.71g (0.7mol) of 4,4'difluorobenzophenone, 84.77g (0.77mol) of hydroquinone and 752g (3.45 mol) of diphenyl sulfone, start the stirring device, place the three-necked flask in the electric heating mantle and feed the high-purity nitrogen with a flow rate of 60ml / min at room temperature. The air was repeatedly replaced, and then the reactant was heated to 150°C at a heating rate of 4°C / min, and then 74.19 g (0.7 mol) of sodium carbonate was added immediately. The reaction temperature was raised to 300°C at a ramp rate of 4°C / min. The temperature of 300°C was maintained until an increase in the viscosity of the reaction mixture to the desired value was observed. Immediately add 1.53 g (0.007 mol) of 4,4'-difluorobenzophenone again for capping to control the molecular weight of the resulting polymer. After an additional twenty minutes, the material was poured into cold distilled water to give a lumpy solid.

Embodiment 3

[0039] Add 130.91g (0.6mol) of 4,4'difluorobenzophenone, 72.66g (0.66mol) of hydroquinone and 700g (3.21 mol) of diphenyl sulfone, start the stirring device, place the three-neck flask in the electric heating mantle and feed high-purity nitrogen with a flow rate of 60ml / min at room temperature, replace the air repeatedly, and then raise the temperature of the reactant at a rate of 6°C / min Add 63.59 g (0.6 mol) of sodium carbonate immediately after heating to 150°C. The reaction temperature was raised to 300°C at a ramp rate of 6°C / min. The temperature of 300°C was maintained until an increase in the viscosity of the reaction mixture to the desired value was observed. Immediately, 1.31 g (0.006 mol) of 4,4'-difluorobenzophenone was added again for capping to control the molecular weight of the resulting polymer. After an additional twenty minutes, the material was poured into cold distilled water to give a lumpy solid.
