  • Polyarylether-based polymer with side chain in methoxypolyethylene glycols structure, solid polymer electrolyte and preparation methods therefor
    Patent number: 11365286
    Abstract: A polyarylether-based polymer with side chain in methoxypolyethylene glycols structure, a solid polymer electrolyte and preparation methods therefore are disclosed. The main chain of the polymer has a polymer structure containing a polyarylether group, the side chain has a methoxypolyethylene glycols structure, and the structural formula of the polyarylether-based polymer is as follows: and the preparation method for the polyarylether-based polymer with side chain in methoxypolyethylene glycols structure comprises: step (1): preparing a polymer containing a polyarylether group; and step (2): dissolving the polymer containing a polyarylether group and methoxypolyethylene glycols in a solvent, then adding a catalyst, dripping a co-catalyst after the catalyst is dissolved, and conducting reaction while stirring to obtain the polyarylether-based polymer with side chain in methoxypolyethylene glycols structure.
