title: Gas chromatographic separation of nitrogen, oxygen, argon, and carbon monoxide using custom-made porous polymers from high purity divinylbenzene.
abstract: Existing porous polymers were surveyed for their ability to separate the subject gases.  Certain products that showed more promise than others were synthesized and the existing synthetic procedures studied and modified to produce new polymers with enhanced ability to separate the subject gases.  Evaluation of the porous polymers was carried out practically by gas chromatography at ambient temperature.  The modified synthetic procedures were somewhat simpler than the originals.  The new porous polymers made with high purity divinylbenzene enabled use of shorter columns to obtain the separations desired.
