摘要： 本文借助于紫外可见光谱、磁化率法和聚合活性测定等方法,研究了BF3·OEt2在镍体系催化丁二烯聚合中的作用。初步探明了BF3·OEt2与Ni(naph)2作用会形成“F-B-Ni”配合物,对形成活性中心不利。

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.
