摘要
用ESR方法对MgCl2负载的钛系Ziegier-Natta催化剂进行了研究，获得了分辩率较好的谱图，并结合前人的工作将信号的归属同钛原子在MgCl2上的负载情况对应起来．同时考察了内外给电子化合物对ESR谱图的影响，探讨了它们可能的作用机理.
ESR spectra of the catalyst for propylene polymerization MgCl2/TiCl4/di - nbutyl phthalate (DNBP)- AlEt3/ diophenyl dimethoxyl silane (DPDMS) with better resolution was obtained. The situations of Ti ions supported on MgCl12 and the assignments of observed signals were correlated. The influence of electron donors on the ESR spectra of catalyst was also investigated.
