Process for producing aromatic polysulfone |
| abstract |
A method for producing an aromatic polysulfone having a low halogen atom content and excellent heat resistance is provided. A method for producing an aromatic polysulfone by a polycondensation reaction of an aromatic dihalogenosulfone compound and an aromatic dihydroxy compound, wherein the polycondensation reaction is performed in the presence of at least one aromatic end-capping agent. When the compounding amount of the aromatic dihalogenosulfone compound is p mole, the compounding amount of the aromatic dihydroxy compound is q mole, and the compounding amount of the aromatic end cap agent is r mole, A method for producing an aromatic polysulfone satisfying (S2). r / (p-q) <2 (S1) p> q (S2) [Selection figure] None |
