Abstract:
The presently disclosed and claimed inventive concept(s) relates to solid catalyst components comprising titanium, magnesium, halogen and an internal electron donor compound having at least one ester group and at least one alkoxy group, and catalyst systems containing the catalyst solid components, organoaluminum compounds, and organosilicon compounds. The presently disclosed and claimed inventive concept(s) further relates to methods of making the catalyst components and the catalyst systems, and methods of polymerizing or copolymerizing alpha-olefins using the catalyst systems.
