Polybenzimidazoles and methods of making and using thereof

2021-03-252021-03-252019-01-29http://hdl.handle.net/10919/102850Disclosed 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.application/pdfenPolybenzimidazoles and methods of making and using thereofPatenthttp://pimg-fpiw.uspto.gov/fdd/92/889/101/0.pdf15269101B01D71/68B01D53/228B01D71/62B01D2256/16B01D2256/18B01D2257/104B01D2257/108B01D2257/11B01D2257/504C07C315/04C08G73/18Y02C20/40Y02P20/15110188992
