## Abstract The MgCl~2~/SiO~2~ complex support was prepared by spray drying using alcoholic suspension, which contained MgCl~2~ and SiO~2~. The complex support reacted with TiCl~4~ and diβ__n__βbutyl phthalate, giving a catalyst for propylene polymerization. The catalyst was spherical and porous wi
## Abstract This article demonstrates the influence of the molar ratio between diether as internal donor and Magnesium dichloride in processing of the catalyst preparation on the catalytic performance for propylene polymerization with MgCl~2~βsupported ZieglerβNatta catalyst. The effect of electron
