A mixture of acrylamide (AM) and acrylic acid (AA) monomers was grafted on gelatinized Amaranthus starch using potassium persulfate (KPS) as an initiator to yield superabsorbent. The effects of different parameters such as time, temperature, monomer feed (AM:AA), starch:monomers ratio and initiator...
