Synthesis and study of magnesium complexes derived from polyacrylate and polyvinyl alcohol and their applications as superabsorbent polymers

Abstract Novel superabsorbent polymers (SAPs) were created by solution polymerization at ambient temperature using potassium polyacrylate (KPA), polyvinyl alcohol (PVA), and magnesium chloride as a cross-linking agent with different weights of 0.4, 0.5, 0.6, 0.7, 0.8, 1 g for KPA 0.33, 0.44, 0.55, 0.733, 1.1 PVA. Fourier transforms infrared (FTIR) UV-Vis spectroscopy used to determine the chemical composition SAP complexes. The outcomes revealed that PVA successfully interacted chloride. morphology surfaces shows uniform porous interconnected microstructure field emission scanning electron microscopy. effective preparation was confirmed thermal characterization (thermogravimetric analysis differential calorimetry) SAPs. influence cross-linker on SAPs’ water absorbency examined. (Mg-PA) (0.6 MgCl 2 ) has maximum swelling capacity 650%, while (Mg-PVA) (0.55 244%. findings SAPs have excellent water-retaining capabilities. strategy in this investigation may function model developing widespread usage agriculture horticulture.
