Reaktionsschritte

To DMF were added 2.1 g of 1-ethylimidazole and 5.0 g of 2-chloroethanesulfonyl chloride. This mixture was stirred at room temperature for 12 hours. The resultant reaction mixture was concentrated under a reduced pressure and then added dropwise to ether to obtain 1-ethyl-3-chlorosulfonylethylimidazolium chloride as a reddish-brown substance. To this reaction product was added 20 g of a 10% aqueous poly(allylamine) solution, followed by 200 ml of water. The mixture was reacted at 100° C. for 2 days in the presence of NaOH in an amount equivalent to the amino groups. To the resultant reaction mixture was added 100 ml of ethanol. After this mixture was allowed to stand at 0° C., the yellow powder precipitated was recovered by centrifuging to obtain a poly[allylsulfonamide-ethyl(1-ethyl)imidazolium]. To the thus-obtained molten salt polymer was added LiTFSI. Thus, a polyelectrolyte represented by the following formula was obtained. ##STR12##
