  • Metallocene catalyst and catalyst system for producing polypropylene blend of iso- and syndio-tactic polypropylene
    Patent number: 6518377
    Abstract: 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 with the catalyst system.
    Type: Grant
    Filed: September 1, 2000
