| Abstract: | In this paper, we study the separation properties of five polymer membranes i.e. polyphenyl-as-triazine, polyphenylquinoxaline containing ether linkage, polyphenylquinoxaline, polyimide and" polypyrrone for O2, N3, H3, CO2 CO and CH4. Though the gas permeabilities P of these membranes for O2 are only 10-10cm3 (STP) .cm/cm2.sec.cm Hg in magnitude, but their selective separation factors αo2/N2e greater than 5. It is worth notice that the selective separation factors of polypyrrone αH2N2. αH2/co and αH2/CH4 are equal to 1181, 1166, 875 respectively. To thr authors knowledge, these have not been reported in previous literature. |
