  The present invention discloses a catalyst component for propene polymerization, comprising titanium, magnesium, halogen, and internal electron donor A, wherein said internal electron donor A is selected from the compouns as shown in Formula I, in Formula I, R is selected from hydrogen, hydroxyl, and substituted or unsubstituted C1-C30 hydrocarbyl, preferably from hydrogen, hydroxyl, and substituted or unsubstituted C1-C20 alkyl, C6-C30 aryl, C6-C30 heteroaryl, C7-C30 alkylaryl and C7-C30 arylalkyl; R1 and R2 may be identical to or different from each other, and are selected from hydrogen and substituted or unsubstituted C1-C30 hydrocarbyl, preferably from hydrogen and substituted or unsubstituted C1-C20 alkyl, C6-C30 aryl, C7-C30 alkylaryl and C7-C30 arylalkyl. According to the present invention, by using the compound as shown in Formula I as internal electron donor compound for propene polymerization, the catalyst has a higher activity, and a slow rate of delay of activity. The obtained polymer has not only a wider molecular weight distribution, but also a high melt index and isotacticity.

  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.
