【Abstract】 The graft copolymerization of soluble starch was carried out using potassium diperiodatocuprate(Ⅲ) as the initiator in alkaline medium. It was found that Cu(Ⅲ)-starch system was an efficient redox initiator for the graft copolymerization. The effect of initiator concentration, monomer concentration, reaction temperature on graft copolymerization was investigated. IR and thermal analysis have determined the structure of the graft copolymer更多还原
