Embodiments of the invention generally include multi-component catalyst systems, polymerization processes and heterophasic copolymers formed by the processes. The multi-component catalyst system generally includes a first catalyst component selected from Ziegler-Natta catalyst systems including a diether internal electron donor and a metallocene catalyst represented by the general formula XCpCpMA, wherein X is a structural bridge, Cpand Cpeach denote a cyclopentadienyl group or derivatives thereof, each being the same or different and which may be either substituted or unsubstituted, M is a transition metal and A is an alkyl, hydrocarbyl or halogen group and n is an integer between 0 and 4. The multi-component catalyst system further includes a second catalyst component generally represented by the formula XCpCpMA, wherein X is a structural bridge, Cpand Cpeach denote a cyclopentadienyl group or derivatives thereof, each being the same or different and which may be either substituted or unsubstituted, M is a transition metal and A is an alkyl, hydrocarbyl or halogen group and n is an integer between 0 and 4 and wherein the second catalyst component exhibits a higher ethylene response than the first catalyst component.

Multi-component catalyst systems and polymerization processes for forming in-situ heterophasic copolymers and/or varying the xylene solubles content of polyolefins

Catalyst systems and methods of forming the catalyst systems are described herein. The methods generally include contacting a support material with an activator to form a support composition, contacting a component with at least a portion of an aluminum containing compound including TIBAl, wherein the component is selected from the support composition, the transition metal catalyst compound and combinations thereof and contacting the support composition with a transition metal catalyst compound to form a supported catalyst system.
