    Abstract: Non-phthalate compounds having a structure represented by the general formula (I) and a method for using same are provided as electron donors in the Ziegler-Natta type catalyst system for the homopolymerization or copolymerization of alpha olefins. The non-phthalate compounds may be used in the preparation of the solid catalyst component, thus serving as "internal electron donors", or employed during or prior to polymerization as "external electron donors", and therefore they can be used to prepare phthalate-free polyolefins.

    Abstract: 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.
