- Abstract
- The polymerization of itaconic acid is generally characterized by a slow polymerization rate and poor networkformation. This results in a polymer with low absorption properties. To improve absorption properties and for use in thehygiene industry, we have been researching superabsorbent polymers (SAPs) based on itaconic acid precursors. In this study,poly(itaconic acid-co-acrylic acid) composites using cellulose, a natural polymer, were synthesized by aqueous solutionpolymerization, and the surface-crosslinking of the SAP composites was introduced. We characterized the structure of SAPcomposites using Fourier transform infrared (FT-IR) spectroscopy. We also measured absorption properties such ascentrifuge retention capacity (CRC), absorbency under load (AUL), and permeability in 0.9 wt.% saline solution. Weconfirmed the synthesis conditions of SAP composites by crosslinker type, cellulose content, and surface-crosslinkingconditions. We found the best performance of an SAP with a CRC of 27.8 g/g, AUL of 21.1 g/g, and permeability of 61 s at5 g input cellulose. In addition, surface characteristics were evaluated by scanning electron microscopy, and thermalstabilities were analyzed by thermo gravimetric analysis.
