Metallocene catalyst and catalyst system for polymerizing an olefin having at least 3 carbon atoms |
摘要 |
A polyolefin metallocene catalyst which includes two metallocene components, a stereorigid isospecific metallocene catalyst component and a stereorigid syndiospecific metallocene catalyst component, both of which are supported upon the same support. A method of forming a catalyst system includes contacting the above catalyst with a cocatalyst or Lewis acid. A method of polymerization includes contacting an olefin of at least 3 carbon atoms with the catalyst system.
