Abstract: The effects of BF3·OEt2 in nickel catalyst system on the polymerization of butadiene were studied by UV-VIS spectra and magnetic susceptibility" measurements. It has been preliminarily proved that BF3·OEt2 can react with Ni(naph)2 forming a so called F-B-Ni complex which is disadvantageous to the formation of the activity center for polymerization.
