Synthesis of wheat straw cellulose-g-poly (potassium acrylate)/PVA semi-IPNs superabsorbent resin

► Semi-IPNs superabsorbent resin (SAR) was prepared by wheat straw cellulose. ► SAR used in agriculture that can improve the water retentivity of soil. ► Polyvinyl alcohol can enhance the mechanical toughness properties of SAR. ► The effects of synthesis conditions on water absorbency were studied.
