Crosslinking DM-β-CD with various types of diisocyanates realizes urethane-crosslinked DM-β-CD polymers. The 4,4′-methylenebis(phenyl isocyanate) (MDI) and 1,4-phenylene diisocyanate (PDI)-crosslinked DM-β-CD polymers show high adsorption capabilities toward PCBs (TeCBs, PeCBs and HeCBs) in isooctane. Similarly, the MDI-crosslinked DM-β-CD polymer shows a high adsorption capability toward 2,2′,3,3′,5,5′-HeCB in insulating oil.
