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 posttreatment 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.
