Title:
HIGH-DURABILITY SOLID POLYMER ELECTROLYTE AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2005002188
Kind Code:
A
Abstract:

To obtain a high-durability solid polymer electrolyte which contains no ether bond, comprises only a fluorocarbon chain and a sulfonic acid group being an electrolytic group and has high molecular weight and a low equivalent weight and to provide a method for producing the same.

The high-durability solid polymer electrolyte comprises a first repeating unit represented by general formula -{C(Z1)(Z2)-C(Z3)(Z4-SO3H)}- (Z1, Z2, Z3 and Z4 are F or Rf1, F or Rf2, F or Rf3 and nothing or Rf4, respectively; Rf1-Rf4 are each a 1-10C perfluoroalkyl group) in a polymer chain and has equivalent weight of ≤2,500 g/equivalent.
