Method for producing crystalline polyether |
| abstract |
(57) [Summary] [Objective] To provide a method for producing a crystalline polyether which can increase the polymerization concentration and greatly improve the productivity. In a method for producing a crystalline polyether by reacting an aromatic dihalide compound and an aromatic dihydroxy compound with an alkali metal compound in an amide-based neutral polar solvent, the reaction system is pressurized and produced from the reaction system. A method for producing a crystalline polyether in which the polymerization reaction is promoted by exhausting water or water and carbon dioxide. |
