PURPOSE:To obtain a solid polyelectrolyte excellent in heat resistance, low- temperature properties and mechanical properties by mixing a specified polymeric compound with an alkali (alkaline earth) metal salt. CONSTITUTION:A solid polyelectrolyte is formed by mixing a specified polymeric compound with an alkali metal salt or an alkaline earth metal salt, wherein the polymeric compound is a polyparabanic acid or its imino precursor having segments (I) comprising repeating unit of formula I or comprising segments (I) and segments (II) comprising repeating units of formula II. In the formulas, Ar and Ar' are different bivalent aromatic groups; and X is NH or O. Examples of the desired alkali metal salts and alkaline earth metal salts include LiClO4, LiBF4, LiAsF6, Li[CF3SO3], LiI, LiBr, and LiPF6. |
