Abstract
A high selectivity and high CO2 plasticization resistant polymer comprises a plurality of repeating units of formula (I) for gas separation applications. The polymer may be synthesized from a superacid catalyzed poly(hydroalkylation) reaction. Membranes made from the polymer and gas separation processes using the membranes made from the polymer are also described.
Claims19
A process for separating at least one gas from a mixture of gases, the process comprising:
- (a) providing a membrane made from the polymer comprising a plurality of repeating units of formula (I)
- (b) contacting the mixture of gases to one side of the membrane to cause said at least one gas to permeate the membrane;
- and
- (c) removing from the opposite side of the membrane a permeate gas composition comprising a portion of said at least one gas which permeated the membrane.
