Superabsorbent polymer with enhanced gel strength and heat resistance using itaconic acid‐based oligomer

The preparation of an itaconic acid-based oligomer and its polymerization with acrylic acid via aqueous solution copolymerization are described herein for application as novel superabsorbent polymers (SAPs). structure the SAP is characterized using Fourier transform infrared (FT-IR) spectroscopy. In addition, absorption properties SAPs various contents degrees monomer neutralization evaluated by measuring free absorbency, centrifuge retention capacity (CRC), absorbency under load (AUL) in 0.9 wt% saline solution. Further, gel strengths thermal stabilities examined rheological thermo gravimetric analyses. results demonstrate that introduction IA-based into network improves AUL, strength, stability SAP. We found best performance a CRC 36.7 AUL 22.7 g/g.
