摘要：
Superabsorbent polymer (SAP) products for use in agricultural applications, and methods of making and using the same are disclosed. Certain of the SAPs include a monomer or a mixture of monomers, selected from acrylic acid, acrylamide, acrylonitrile, methacrylamide, 2-acryloamido-2-methyl-propanesulfonic acid, methacrylic acid, vinyl sulfonic acid, ethyl acrylate, potassium acrylate, derivatives thereof or mixtures thereof, that is graft polymerized onto a starch in the presence of an initiator to form a starch graft copolymer.
