  Improved Ziegler-Natta catalysts and methods of making the improved catalyst are described. The Ziegler-Natta catalyst is formed using a spherical MgCh-xROH support, where R is a linear, cyclic or branched hydrocarbon unit with 1-10 carbon atoms and where ROH is an alcohol or a mixture of at least two different alcohols and where x has a range of 1.5 to 6.0, preferably 2.5 to 4, more preferably 2.9 to 3.4, and even more preferably 2.95 to 3.35. The Ziegler-Natta catalyst includes a Group 4-8 transition metal and an internal donor comprising a phthalate-free diether compound. The catalyst has improved activity in olefin polymerization reactions as well as good stereoregularity and hydrogen sensitivity, and may be useful in the production of phthalate-free propylene polymers having a molecular weight distribution (PI(GPC)) in the range from about 5.75 to about 9.

  A method for making a solid catalyst component for use in a Ziegler-Natta catalyst includes combining in a hydrocarbon solvent a porous particulate support with a hydrocarbon soluble organomagnesium compound to form a suspension. The organomagnesium compound is halogenated followed by addition of an alcohol and the mixture is then reacted with a titanium compound followed by a reaction with at least one diether compound to form the solid catalyst component. Afterwards the reaction product is extracted with a mixture of a titanium compound and a hydrocarbon solvent. The solid catalyst component recovered is combined with an aluminum cocatalyst to form a Ziegler-Natta catalyst system for the polymerization of olefins. In particular, the catalyst system including a diether internal electron donor may have an activity and hydrogen response suitable for the production of propylene polymers having a molecular weight distribution (PI(GPC)) in the range from about 5.75 to about 9.
