METHOD FOR PREPARING POLYARYLSULFONE ETHER ON BASIS OF DOUBLE-END-CAPPING METHOD

Resumen de: WO2025213651A1

The present invention relates to a method for preparing polyarylsulfone ether on the basis of a double-end-capping method. In the method, a bifunctional phenol and a bifunctional halogenated arylsulfone are used as raw materials, and are subjected to a condensation polymerization reaction in an organic solvent in the presence of an inorganic caustic alkali or inorganic caustic salt to prepare polyarylsulfone ether. After the molecular weight of the polyarylsulfone ether reaches a preset value, a halogen-eliminating metal phenate end-capping agent is added to a polymerization system, thereby removing an end group of a halogen atom and also achieving control over the molecular weight distribution during polymerization; and after a predetermined molecular weight is reached by means of condensation polymerization, a high-activity metal-phenate-removing aromatic end-capping agent is added to the polymerization system to remove a metal phenate end group and terminate the condensation polymerization reaction, and to make the polyarylsulfone ether have an aromatic end group and also contain necessary functional groups during end-capping. The obtained polyarylsulfone ether not only has good comprehensive performance, but can also meet the subsequent requirements of application fields; and by using end-capping agents containing corresponding functional groups, the requirements of different application scenarios for the polyarylsulfone ether can be met by means of the end-capping reacti
