| Abstract: | The copolymerization of acrylonitrile and butyl methacrylate by Fe(acac)_3-Al(i-Bu)_3 catalyst and the structure of the copolymer were presented.Copolymerization were carried out under nitrogen atmosphere using syringe technology.Copolymer was characterized by IR and DTA.Copolymerization could be performed in solvents such as aromatic hydrocarbon and alkane.The yield was the highest in THF.Molecular weight distribution and molecular weight of copolymer were changed with the change of acrylonitrile/butyl methacrylate molar ratio.The suitable Al/Fe molar ratio was 10.The kinetic studies indicated that copolymerization was approximately first order with respect to(monomer) concentration.The apparent activation energy of copolymerization was 46.1 kJ/mol. |
