GRAFT COPOLYMERIZATION OF METHYL ACRYLATE ONTO NYLON 1010 INITIATED WITH POTASSIUM DIPERIODATOARGENTATE(III)

Many studies have been reported on oxidation of some molecules by potassium diperiodatoargentate(III),in which most experts think that the mechanism of oxidation is a two electron transfer process without radicals, and Ag(III) cannot initiate polymerization of monomers. However, under our experimental conditions the results show that the polymerization of monomers such as acrylamide, acrylonitrile can be initiated by Ag(III) redox system. In this paper, graft copolymerization of methyl acrylate (MA) onto nylon 1010 is carried out by using potassium diperiodatoargentate(III) as the initiator. It is found that Ag(III) nylon 1010 system is an efficient redox initiator for the graft copolymerization. The effects of temperature. time and concentrations of initiator and monomer on the reaction are investigated. A single electron transfer mechanism is proposed to explain the formation of radicals and the initiation.
