    Abstract: 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 XCpACpBMAn, wherein X is a structural bridge, CpA and CpB each 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 XCpACpBMAn, wherein X is a structural bridge, CpA and CpB each 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.
