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 the authors knowledge
these have not been reported in previous literature.
