ABSTRACT:
Crosslinked poly(amino acids) useful as superabsorbent polymers and an improved process for preparing the crosslinked poly(amino acids) is disclosed. Use of polyaziridine and polyepoxide crosslinkers allows the production of superabsorbent polymers that is free of special handling steps required to process hydrogel materials using conventional preparation methods.
