摘要：

Recently we successfully established the first structure-performance relationships between the catalyst surface area and propylene polymerization activity using novel MgO/MgCl2/TiCl4 core-shell catalysts with nonporous and non-fragmentable features. In the present paper, we have addressed the physical and chemical natures of these novel model catalysts in comparison with typical Ziegler-Natta catalysts, by means of comprehensive characterization and analyses. It was clarified that the MgO/MgCl2/TiCl4 core-shell catalysts offer an ideal and powerful tool to address relationships between the support architectures and polymerization performance, which had been long un-clarified.
