Description

General description

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

Porous polymers are the most suitable adsorbent for applications based on the analysis of gases, acids, amines, organics of low carbon number and water.[1]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.[2] 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).[3] Furthermore they are relatively inert and exhibit hydrophobicity.[4] HayeSep B is a copolymer of divinylbenzene and polyethylene.[5]

Application

HayeSep B can maybe used in combination with HayeSep A for separation of a gaseous mixture comprising of hydrogen and hydrogen sulphide.^[5]
