摘要

聚苯基-1

4-三嗪(PPT)、聚苯基单醚喹嗯啉(PPQ(E))、聚苯基喹哑心啉(PPQ(B))、聚酰亚胺(PI)和聚苯并咪唑吡咯酮(PY)均是耐高温高分子。本文制备了这些高聚物的均质膜(除PI外)

研完了它们对O2、N2和H2、N2、CO、CH4的分离性。

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

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.
