HayeSep^® Porous Polymer Adsorbent

Porous polymers are the most suitable adsorbent for applications based on the analysis of gases, acids, amines, organics of low carbon number and water. They are best suited for gas chromatography and are basically copolymers of polydivinylbenzene (DVB) which are very porous in nature ranging from mesoporous to microporous.HayeSep^® has a high surface area owing to its micropores thereby making it a suitable candidate for separation of gases and volatile organic compounds (VOCs).Furthermore they are relatively inert and exhibit hydrophobicity. HayeSep S is a copolymer of DVB-4-vinyl-pyridine.

HayeSep porous polymers, considered second generation materials, are consistent batch-to-batch, with minimal shrinkage and monomer bleed.

HayeSep S was used for the analysis of hydrocarbons to check the microbial production of propane and ethane in the deep marine sediments. It was also used for methyl acetate hydrogenolysis activity experiments which were performed in a gas flow set-up to study the relation between reduction temperature and activity in copper catalysed ester hydrogenolysis and methanol synthesis.
