| titleOfInvention | Catalysis system for olefin polymerization reaction |
| abstract | The present invention relates to a catalysis system for an olefin polymerization reaction. According to the present invention, a titanium-containing solid granular catalyst component adopting a carboxylic ester compound as an internal electron donor is added with an alkenyl trialkoxy silane compound and a dialkyl dialkoxy silane compound during olefin polymerization, wherein the alkenyl trialkoxy silane compound and the dialkyl dialkoxy silane compound are adopted as the composite external electron donor, such that the high activity and the high directional capability of the catalyst can be maintained, the hydrogen response of the catalyst is substantially improved, especially in the case of requirement of direct polymerization to obtain the high melt index polymer, and the polymerization method is simple. |
