Explanation of polymer sample codes.
| Samples Code | Description |
|---|---|
| SS | Soluble starch |
| CS | Corn starch |
| CAN | Ceric ammonium nitrate |
| KPS | Potassium persulfate |
| MBA | N,N’-methylenebisacrylamide |
| SS-g-PAA(12/CAN) | Soluble starch-g-poly(acrylic acid) with ceric ammonium nitrate and the precipitated end product was left in the dark for 12 h in a solution of deionized water and ethanol and later separated from post reaction mixture. |
| SS(12)-g-PAA (CAN) | Soluble starch-g-poly(acrylic acid) with ceric ammonium nitrate and the superabsorbent was cooled for 12 h at 4 °C and then precipitated. |
| SS-g-PAA (CAN) | Soluble starch-g-poly(acrylic acid) with ceric ammonium nitrate and the product was washed with ethanol and distilled water immediately. |
| SS-g-PAA (KPS) | Soluble starch-g-poly(acrylic acid) with potassium persulfate and the product was washed with ethanol and distilled water immediately. |
| CS-g-PAA (CAN/U/NaOH) | Corn starch-g-poly(acrylic acid) with ceric ammonium nitrate and the product was prepared in deionized water and NaOH solution. |
| CS-g-PAA (KPS/U/NaOH) | Corn starch-g-poly(acrylic acid) with potassium persulfate and the product was prepared in deionized water and NaOH solution. |
