Abstract:The polymerization of acrylonitrile (AN) initiated by diperiodatoargentate(Ⅲ) com-plex-acetylacetone(AA) redox system in agueous alkaline medium was studied.The rate of polymerization(Rp)was determined at different AN concentration , Ag(Ⅲ) concentration, pH value of the medium and temperatures. Meanwhile,the influence of initiator on molecular weight of polymer was measured. Furthermore, based on these experimental results , an initiation mechanism was proposed.
Keywords:Depriodatoargentate (Ⅲ)  Acetylacetone  Acrylonitrile  Redox ini-tiation
