PRODUCTION OF RUBBER ELASTIC COPOLYMER, ION CONDUCTIVE THIN FILM COMPOSITION CONTAINING THE SAME, ION CONDUCTIVE THIN FILM AND ITS PRODUCTION, AND SOLID ELECTROCHEMICAL ELEMENT CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain the subject composition having excellent mechanical characteristics, a strong adhesive force, capable of being processed in the form of a solution, and having the characteristic of rubber elasticity by mixing a specific styrene-maleic acid polyethyleneoxy ester copolymer, a specific electrolytic salt, and an organic solvent. ;SOLUTION: This composition comprises (A) 1-50 wt.% of a styrene-maleic acid polyethyleneoxy ester copolymer of formula I {R is H or a ≤10C alkyl including methyl; (a)-(d) are each 0 or 1, provided that (a)+(b)+(c)+(d)=1; R' is R or a group of formula II [(n) is 1-20]}, (B) 1-50 wt.% of an electrolytic salt selected from compounds of the formula: A+B- (A+ is an alkali metal cation such as lithium cation; B- is an anion such as ClO4-), and (C) 50-98 wt.% of an organic solvent selected from acetonitrile, propylene carbonate, dimethoxyethane and tetrahydrofuran.;COPYRIGHT: (C)2000,JPO
