| Abstract: | Graft copolymerization of methyl acrylate(MA) ont o Nylon-66 was carried out using potassium diperiodato argentate(Ⅲ)as the initiator. It was found that Ag(Ⅲ)-Nylon-66 system is an efficient redox initiator for the graft copolymerization. The effects of temperature, concentration of initiator and monomer on the reaction were investigated. A two-step single electron transfer mechanism was proposed to explain the formation of free radicals and the initiation. |
