Abstract
Titanium-magnesium catalysts (TMC), containing monoester (ethyl benzoa te) as internal donor, can be transferred to the diester TMC by the tr eatment with TiCl4 and dibutyl phthalate. The activity and the stereos pecificity of the transferred TMC in propylene polymerization are clos e to those of TMC prepared directly in the presence of diester. The su rface area and the porous structure of both types of TMC were studied and the correlation with the activity of these catalysts is discussed.
