Although nanometer-sized and defective δ-MgCl2 supports are indispensable for Ziegler-Natta catalysts, their formation process has not been fully elucidated. In this study, we investigated the formation of nanostructures and active surfaces of Ziegler-Natta catalysts using a multifaceted approach including chemical composition analysis and polymerization tests in addition to total X-ray scattering and various spectroscopic methods. It led us to approach the significance of each step in the preparation method, which has been empirically improved over a long history.
