PREPARATION METHOD OF SULFONATED POLYBENZIMIDAZOLE AND SULFONATED POLYBENZIMIDAZOLE PREPARED THEREFROM, AND POLYMER ELECTROLYTE MEMBRANE COMPRISING THE SAME

摘要

The present invention is a sulfonated poly-benzimidazole method and from which the imidazole prepared sulfonated poly-benzimidazole imidazole, and relates to a polymer electrolyte membrane including the same, and more particularly to the formula (1) or to the production of the monomer represented by the following formula (2) includes the step of sulfonating a polymerization monomer represented by the formula (3) polybenzimidazole how and from which manufactured the sulfonated poly-Benz is already on the imidazole and the polymer electrolyte membrane comprising the same. ; [Formula 1] ; [Formula 2] ; [Formula 3] ; In Formula 1 to 3, Y ₁ , and Y ₂ are each hydrogen, alkyl or aryl, and the straight-wind a hydrogen, an alkyl or aryl group having 1 to 12 carbon atoms, R is SO ₂ and or CO, X is being chlorine (Cl) or fluorine (F)
