摘要：
The present invention relates to catalyst systems containing solid catalyst components comprising titanium, magnesium, halogen and a 1,8-naphthyl diaryloate internal electron donor compound; organoaluminum compounds and alkyl benzoate derivatives as external electron donors. The present invention also relates to methods of making the catalyst systems, and methods of polymerizing or copolymerizing alpha-olefins using the catalyst systems.
