- Abstract
Chestnut shell pigment was employed to modify a polyacrylamide superabsorbent. The synthesis was conducted through free-radical polymerization in aqueous solutions by using N, N'-methylene bisacrylamide and ammonium persulfate as a crosslinker and an initiator, respectively. This work focused on the optimization of the synthesis conditions by surface response methodology. The effects of the doses of chestnut shell pigment, crosslinker, and initiator on the water absorbency of the superabsorbent were studied. The optimized condition was found to be 14.47% of the acrylic acid, 0.16% of the chestnut shell pigment, 0.71% of the crosslinker, 0.32% of the initiator, 4.06 % of NaOH, and 80.28% of H2O in quality percentage, under which the water absorbency was 264.2g/g
