DIBENZYLATED POLYBENZIMIDAZOLE BASED POLYMER AND METHOD FOR PREPARING THE SAME

摘要

The present invention relates to a dibenzylated polybenzimidazole-based polymer and a producing method thereof. A polybenzimidazole-based polymer in which substituted or non-substituted benzyl groups are introduced to the two nitrogen atoms of benzimidazole ring. The benzimidazole ring is not decomposed by the attack of hydroxide ions but exhibits excellent alkali resistance, and thus maintains high ion conductivity.
