Disclosed are polybenzimidazoles containing sulfonyl groups. The polymers can be synthesized in Eaton's reagent from 3,3′,4,4′-tetraaminodiphenylsulfone, which itself can be synthesized from 4,4′-dichlorodiphenylsulfone. Methods of synthesizing the polymers are disclosed. The disclosed polymers can be used for high temperature H2/CO2 separation membranes and other uses.
本发明公开了含有磺酰基的聚苯并咪唑。这种聚合物可在伊顿试剂中由 3,3′,4,4′-四氨基二苯砜合成,而四氨基二苯砜本身可由 4,4′-二氯二苯砜合成。公开了聚合物的合成方法。所公开的聚合物可用于高温 H2/CO2 分离膜和其他用途。
