Gas and water vapor separation properties of a systematic series of sulfonyl-containing

poly(benzimidazole)s are reported as a function of pressure and temperatrue. Gas separation properties are reported

over temeratures ranging from ambient up to 190C. Additionally, separation properties of PBIs blended with

polyimides are also reported, with some blends exhibiting transport properties above the 2008 upper bound.
