Abstract: The graft copolymerization of acrylonitrile (AN) onto polyacrylamide (PAAM) was studied by using potassium diperiodatocuprate (Ⅲ) as the initiator. It was found that potassium diperiodatocuprate-PAAMcomplex is an efficient redox initiator for the graft copoiymerization. The effects of the temperature, concentration of initiator and monomer (AN) on the reaction were investigated. Under the optimum conditions the efficiency of graft exceeds 95% and the graft percent of PANin copolymer reaches 80%. The initiation mechanism is proposed.
