Abstract
Disclosed are a catalyst component for olefin polymerization comprising titanium, magnesium, a halogen, internal donors, in combination with a silane and oxalic acid diamides of the following formula: An olefin polymerization catalyst system consisting of the solid catalyst component, an organoaluminum compound, and an optional external electron donor compound is also disclosed. Employment of both oxalic acid diamides and silane component in the presence of internal electron donors as an elements of solid Ziegler-Natta type catalyst composition enhances stereo-specificity while maintaining excellent catalyst activity and hydrogen response, in which the modified catalyst composition produces polypropylene with good productivity and higher stereo-specificity than catalyst composition without such modification.
