PURPOSE:To provide the title polyelectrolyte which allows electric current capable of being put to practical use to flow therethrough, by introducing an org. group having amino group into a phosphazene skeleton. CONSTITUTION:A solid polyelectrolyte is obtd. by mixing a polyphosphazene mainly composed of recurring units of formula I [wherein R is an aliph. alicyclic or arom. group which may have at least one substituent and at least 10% of R is a group of formula II (wherein R1 is a substd. or unsubstituted aliph., alicyclic or arom, group)] with a metal salt (e.g. LiSO3CF3, NaSCN, KNO3, etc). in an molar ratio of the recurring unit of the polymer to the metal salt of 10<4>-0.2. The polyelectrolyte has greatly improved ion conductivity as compared with conventional solid polyelectrolytes, allows electric current capable of being put to practical use to flow therethrough and can be widely used for medical use, chemical use, etc. in addition to electrical and electronic fields such as electrolyte for batteries. |
