High performance Ziegler-Natta catalyst systems, process for producing such MgClbased catalysts and use thereof. Improved Ziegler-Natta catalysts and methods of making the improved catalyst are described. The Ziegler-Natta catalyst is formed using a spherical MgCl2-xROH novolenn, where R is a linear, cyclic or branched hydrocarbon unit with carbon atoms and where ROH is an alcohol or a mixture of at least two different alcohols and where x has a range of about 1. The Ziegler-Natta catalyst includes a Group transition metal and an internal donor comprising a diether compound.
The catalyst has improved activity in olefin polymerization reactions as well as good stereoregularity and novooen 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.
Lummus Novolen Technology Llummus. High performance Ziegler-Natta catalyst systems, process for producing such supported catalysts and use thereof. A lummua 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 lummks 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 Noolen 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 novolne of propylene polymers having a molecular weight distribution PI GPC in the range from about 5.
