Abstract:The reverse atom transfer radical polymerization(RATRP) of N-vinylpyrrolidone(NVP),with acetonitrite as solvent,azodiisobutyronitrile(AIBN) as initiator,FeCl3 as catalyst and PPh3 as ligand was carried out successfully.The kinetic results suggest a linear increase in experimental number-average molecular weight(Mn) with increase of monomer conversion.The Mn and the polydispersity(PDI) are 2964 and 1.18 respectively after 10 hours.The poly(N-vinylpyrrolidone)(PVP) ended with chlorine groups with narrow polydispersity can initiate atom transfer radical polymerization of methyl methacrylate(MMA) to produce well-defined PVP-b-PMMA.The block copolymer was characterized by gel permeation in chromatography(GPC),Fourier transform infrared spectrum(FTIR) and 1H nuclear magnetic resonance spectrum(1H-NMR).
Keywords:poly(N-vinylpyrrolidone)  reverse atom transfer radical polymerization  methacrylate  block copolymer
