| Abstract: | Spherical MgCl_2 support was prepared at a low stirring dispersion speed in a self-designed magnetic stirring reactor. SEM measurement showed spherical support had nice morphology. The particle size distribution of the support was even. The ethanol and water mass fraction of the support were determined through the thermogravimetry. Spherical supported Ziegler-Natta catalysts for propylene polymerization showed a high activity, obtaining spherical polypropylene particles. |
