摘要：
Acid gases are separated from a gas stream by bringing the gas stream into contact with a multilayer composite membrane comprising a nonselective polymeric support layer and an active separating layer comprising a polyelectrolyte polymer which contains cationic groups which are electrostatically associated with anions for which the pK.sub.a of the conjugate acid is greater than 3.
