Permeation of CO 2 was investigated by using synthetic polymeric membranes having a tertiary amine moiety, 2‐( N , N ‐dimethyl)aminoethoxycarbonyl moiety. Permselectivity of the present membranes towards CO 2 was achieved. Through poly{2‐( N , N ‐dimethyl)aminoethyl methacrylate‐ co ‐acrylonitrile} (DMAEMA/AN‐199) membrane, where DMAEMA mol fraction was 0.199, the separation factor towards CO 2 for CO 2 /N 2 separation ranged from 60 to 90, ranging in the CO 2 partial pressure in the feed gas from 61 to 3.6 cmHg. © 1995 John Wiley & Sons, Inc.
