Abstract As a chloromethylation reagent, suspension copolymerization of styrene and vinyl benzene was used to create a number of hypercrosslinked polymeric resins (HPRs). By altering the types of pore-forming agents (toluene or liquid paraffin) and the volume of vinyl benzene, a series of ultra-high cross-linked adsorption resins with different pore structures of HPRs were synthesized. The column breakthrough adsorption experiments demonstrate that the adsorption capacity of HPRs for CS₂is related to the microporous volume between 0.4 and 1nm (0~2nm), but has no obvious correlation with specific surface area and total microporous volume (0~2nm). The temperature-programmed desorption studies reveal that, when the adsorption resin has a higher proportion of mesopores and macropores, the CS₂ desorption becomes easier with a lower peak temperature.
