摘要:
Provided are a sulfonic-acid-containing amine-cured type epoxy resin having at least one structure selected from structures represented by the following formulas (1)and (2) (wherein, R 1 and R 3 each independently represents a hydrocarbon chain having 1 to 50 carbon atoms, or a hydrocarbon chain having 1 to 50 carbon atoms and having a hydroxyl group, amino group, ether bond or imine bond, and R 2 represents a hydrocarbon chain having 3 or 4 carbon atoms); electrolyte or electrolyte membrane containing the resin; method for preparation thereof; electrochemical device using the membrane. The electrolyte and electrolyte membrane according to the present invention have electrolyte properties such as ion conductivity enough for use in electrochemical devices, have heat resistance and mechanical strength, and can be prepared at a low cost. In addition, bonding or adhesion to electrodes is excellent owing to suppressed swelling of the membrane when impregnated with a solvent.
