Abstract
Provided is a superabsorbent structure based on a covalently crosslinked copolymer having a microstructure of a HIPE, and characterized by hydrophobic and hydrophilic segments of at least five residues; the unique chemical and structural properties of the copolymer afford a polymeric superabsorbent structure that is capable of swelling in polar as well as apolar media. Also provided are processes of manufacturing the superabsorbent structure, and uses thereof.
