Preparation of Ethylene Glycol Dimethacrylate (EGDMA)-Based Terpolymer as Potential Sorbents for Pharmaceuticals Adsorption.

Ethylene glycol dimethacrylate (EGDMA) is used as a crosslinker in poly(acrylonitrile (AN)--vinylbenzyl chloride (VBC)) to investigate the effect of long-chain crosslinker to the porosity of the terpolymer system. Poly(AN--EGDMA--VBC) is synthesized by using precipitation polymerization method and further hypercrosslinked by Friedel-Crafts reaction. FT-IR spectra of poly(AN--EGDMA--VBC) show that the absorption bands at ~1290 cm that are assigned to the C-Cl vibrations are almost disappeared in hypercrosslinked (HXL) poly(AN--EGDMA--VBC) polymers, confirming that the hypercrosslinking reaction is successful.
