Membranes for selective gas separation |
| abstract |
The invention concerns a membrane for selective gas separation. The membrane consists of an ethylene oxide copolymer or a polymeric material obtained by crosslinking such a copolymer. Said copolymer is characterised in that it consists of at least 30% in number of —CH 2 CH 2 O— units derived from ethylene oxide, and at least 2% in number of —CHR—CH 2 O— units derived from an oxirane bearing a crosslinkable substituent R and/or of —CHR 1 —CH 2 O— units derived from an oxirane bearing a non-crosslinkable substituent R 1 . The membranes are particularly useful for separating hydrophilic gases contained in a gas mixture. |
