| titleOfInvention | Process for producing polysulfone |
| abstract | A polysulfone is produced in which the melt viscosity is hardly increased during melt processing and the halogen content is low. A dihalogenosulfone compound and a dihydroxy compound are polycondensed in a solvent in the presence of an alkali metal carbonate, and then mixed with a basic compound. The resulting mixture is heated at a predetermined temperature at a predetermined temperature. After mixing with a metal compound that generates water at a temperature, it is mixed with an alkylating agent and / or an aralkylating agent. An aprotic solvent is preferably used as the solvent, and a metal hydroxide is preferably used as the metal compound that generates water. [Selection figure] None |
