Effective Parameters in Surface Cross-linking of Acrylic-based Water Absorbent Polymer Using aromatic and aliphatic epoxy resins

In order to enhance swollen gel strength, surface crosslinking of acrylic-based superabsorbent polymer (SAP) particles is conducted. Modification process contains soaking in treatment solution including water, acetone and cross-linker and sequentially heating at 170˚C. BADGE and CAE have been used as surface crosslinking agents. FTIR-ATR and oscillatory rheometry have been utilized to confirm condensation reaction. Effect of cross-linker content and curing duration on swollen gel strength and swelling properties have been investigated as well
