Studies were conducted on grafting of acrylamide (AM) and sodium allylsulfonate (SAS) onto cornstarch utilizing Ce(IV) as initiator. The influence of synthetic variables on percent grafting and grafting efficiency have been discussed. The starch‐ g ‐poly(AM‐co‐SAS) samples prepared by this method were characterized by IR spectroscopy, scanning electron micrograph, and elemental analysis. These graft copolymers may induce the flocculation of Kaolin suspension and showed excellent ability in both the rates of sedimentation and the clearing of supernatant liquid in the presence of NaCl.
