| Abstract: | he initiation mechanism of ceric ion/2-benzoyl acetanilide system was studiedby means of FT-IR, EPR and kinetic studies which revealed that 2-benzoyl ac-etanilide acts as a very active promotor to the polymerization initiated by ceric ion.The initiation mechanism was then proposed which involved the complex formationbetween a ceric ion and a l ,3-diketone group or a carbamate group, followed by,thedecomposition of the complex to generate C-centered secondary alkyl radical and N-centered anillido radical, both of which would initiate polymerization of vinylmonomer as the end groups of the polymers formed. |
