Abstract:
Polymerization processes and polymers formed therefrom are described herein. The polymerization processes generally include contacting ethylene and propylene with a multi-component catalyst composition including a first catalyst component including a chromium oxide based catalyst and a second catalyst component selected from metallocene and Ziegler-Natta catalysts within a polymerization reaction vessel to form a random copolymer, wherein the second catalyst component exhibits a higher comonomer response than the first catalyst component.
