Abstract: An iron-catalyst system FeCl3-Phen-Al(i-Bu)3 fos butadiene polymerization has beens tudied. The results of magnetic susceptibility and UV-Vis spectra measurements indicated that a high-spin complex FeCl3·(EA)2 was formed from FeCl3 and ethyl acetate(EA). The presence of o-phenanthroline(Phen)stabilizes Fe(Ⅱ),markedly reducing the ferromagnetismof the catalyst system.

Key words: butadiene, polymerization, iron catalyst, magnetic analysis
