ABSTRACT:
Disclosed are solid titanium catalyst components, catalyst systems containing solid titanium catalyst components, and methods of making solid titanium catalyst components. The solid titanium catalyst components contain an internal electron donor compound containing at least one ether group and at least one ketone group. The catalyst system can contain a solid titanium catalyst component, an organoaluminum compound, and an organosilicon compound. Also disclosed are methods of polymerizing or copolymerizing an alpha-olefin. The methods involve contacting an olefin with a catalyst system containing the solid titanium catalyst component.
