Abstract: The graft copolymerization of soluble starch was carried out using potassium diperiodatocuprate(Ⅲ) as the initiator in alkaline medium. It wa s found that Cu(Ⅲ)-starch system was an efficient redox initiator for the graf t copolymerization. The effect of initiator concentration, monomer concentration , reaction temperature on graft copolymerization was investigated. IR and therma lanalysis have determined the structure of the graft copolymer.
