Abstract:
A catalyst system containing (a) a solid catalyst component containing a titanium halide, a magnesium halide, a first internal electron donor compound, and a second internal electron donor compound, (b) an organoaluminum compound, and (c) an external electron donor compound is disclosed. The first internal electron donor compound contains at least one ether group and at least one ketone group. The second internal electron donor compound is a 1,8-naphthyl diester compound. Methods of polymerizing or copolymerizing alpha-olefins using the catalyst system also are disclosed.
