| titleOfInvention | Method for producing aromatic polymer |
| abstract | The present invention is a method for producing a high-quality aromatic polymer by batch-type continuous polymerization, a reaction tank having a raw material supply port and a polymer discharge port, a stirring device, a distillation pipe, a reaction temperature management device, and a reaction pressure management device. When the aromatic raw material is polycondensed to produce an aromatic polymer in a batch system, the temperature of the reactor part in contact with the reaction space is maintained at 150 to 300 ° C. during the polycondensation reaction. The reaction temperature is in the range of 300 to 400 ° C, the temperature is raised from 280 ° C to the final reaction temperature at 0.5 ° C / min or less, and after reaching the final reaction temperature, the internal pressure of the reaction system is reduced to 25 to 200 Torr. Then, polycondensation is performed. |
