As the use of absorbent disposable items such as sanitary
napkins and diapers have increased, environmental
problems related to waste disposal have been concerned. To
resolve this problem, we can use eco-friendly superabsorbent
polymer (SAP) with bio-based monomer replacing petroleum
based SAP. However, bio-based SAPs have low water
absorption properties. In this study, we studied the effects
of post-treatment processes to enhance the performances
of SAPs. The SAPs were prepared using itaconic acid, vinyl
sulfonic acid, tetraethylene glycol diacrylate and ammonium
persulfate initiator. Various post-treatment processes
(Quenching, Aging, and Annealing) are investigated. After post-
treatment processes, we measured free water absorbency,
centrifuge retention capacity, and absorption under load of
the SAPs. The structure of SAPs was confirmed by FT-IR. The
amount of monomer residues of SAP was confirmed by HPLC.
