Embodiment 1
[0025] Example 1 (about 15% solid content)
[0026] Polymerization process:
[0027] In a four-port reaction kettle equipped with a thermometer, a nitrogen pipe, a condensing separator, and an anchor stirrer, first add 50Kg of refined sulfolane, and then add 6.67Kg of 4,4'-difluorobenzophenone and 3.303Kg of p-benzene Diphenol, when it is completely dissolved and the temperature rises to 80°C, add 3.498Kg (over 2%) Na 2 CO 3 , and then add 2Kg of xylene, stir and heat until the temperature rises to 150°C, the system starts to azeotrope, xylene and water condense in the water separator, the upper layer of xylene is refluxed, and the lower layer of water is continuously released, and the water is recovered to the theoretical When measuring, the xylene in the upper layer starts to be clear and transparent, and then continues to reflux for 20 minutes, and then starts to distill the xylene from the system. Continue to increase the viscosity. After 1.5 hours, stop the reactio...
Embodiment 2
[0031] Embodiment 2 (about 26% of solid content)
[0032] Polymerization process:
[0033] In a four-port reaction kettle equipped with a thermometer, a nitrogen pipe, a condensing separator, and a paddle stirrer, first add 25Kg of refined sulfolane, and then add 6.67Kg of 4,4'-difluorobenzophenone and 3.303Kg of p-benzene Diphenol (available polymer 8.64Kg, solid content is about 30%), when it is completely dissolved and the temperature rises to 80°C, add 3.498Kg (excess 2%) Na 2 CO 3 , then continue to heat up, add 2Kg of xylene, stir and heat, until the temperature rises to 150 ° C, the system starts to azeotrope, xylene and water condense in the water separator, the upper layer of xylene is refluxed, and the lower layer of water is continuously released. When the water is recovered to the theoretical amount, the xylene in the upper layer becomes clear and transparent, and the reflux continues for 20 minutes, and then the xylene starts to be evaporated from the system. The...
Embodiment 3
[0037] Example 3 (about 15% solid content) Polymerization process:
[0038] In a four-port reaction kettle equipped with a thermometer, a nitrogen pipe, a condensing water separator, and a propeller stirrer, first add 50Kg of refined sulfolane, then add 6.67Kg of 4,4'-difluorobenzophenone and 3.303Kg Hydroquinone (available polymer 8.64Kg, solid content about 15%), when it is completely dissolved and the temperature rises to 80°C, add 3.498Kg (excess 2%) Na 2 CO 3 , then continue to heat up, add 2Kg of xylene, stir and heat, until the temperature rises to 150 ° C, the system starts to azeotrope, xylene and water condense in the water separator, the upper layer of xylene is refluxed, and the lower layer of water is continuously released. When the water is recovered to the theoretical amount, the xylene in the upper layer becomes clear and transparent, and the reflux continues for 20 minutes, and then the xylene starts to be evaporated from the system. Viscosity increases cons...
