Abstract
Aminated polymers capable of reversibly complexing carbon dioxide and other acid gases including CO.sub.2, SO.sub.2, NO.sub.x and H.sub.2 S, a method of using such polymers and an operational unit including such polymers are disclosed. The polymers incorporate amine group which reversibly complex acid gases. Such polymers provide a significant advantages over presently used sorbents used to remove acid gas.
