METHOD FOR MANUFACTURING POLYETHER POLYMER COMPOSITION, POLYETHER POLYMER COMPOSITION AND SOLID ELECTROLYTE FILM

摘要

PROBLEM TO BE SOLVED: To provide a polyether polymer which does not cause the reduction in molecular weight by molecular chain scission on storage and molding, its manufacturing method, and a solid electrolyte film having excellent mechanical properties which is obtained by molding the composition. SOLUTION: The polyether polymer composition is obtained by dispersing an antioxidant insoluble in an organic solvent into a slurry obtained by the slurry polymerization of an oxirane monomer in the above organic solvent, and successively removing the above organic solvent. The solid electrolyte film is obtained by compounding an electrolyte salt compound with the composition and subjecting the resulting compound to extrusion molding. COPYRIGHT: (C)2004,JPO&NCIPI
