Abstract: Recent progress of the eerie ion redox initiation systems and eerie ion inititated graft copolymerization and block copolymerization are briefly reviewed. The eerie ion redox initiation systems include: Ce⁴⁺/amide, Ce⁴⁺/carbamate, Ce⁴⁺/carbonyl compound. The graft copolymerizations are graft copolymerization of vinyl monomers onto macromolecules having phenylcarbamoyl or p-tolycar-bamoyl pendant groups and the graft copolymerization of poly (ether-urethane) initiated with eerie ion. The block copolymerization of macromolecules with active terminal groups such as aldehyde using eerie ion as initiator. The reaction mechanism are proposed based on the ESRstudies and the IRend group analysis of polymer obtained.

Key words: Ceric ion redox initiation system, Ceric ion initiated graft copolymerization, Ceric ion initiated block copolymerization, Vinyl radical polymerization
