| 发明名称 | Catalyst component for polymerization of olefin and preparation method | ||
| 摘要 | The present invention relates to a catalyst component for olefin polymerization, which comprises the reaction product of at least one organo-magnesium compound, at least one titanium-containing compound, at least one hydroxyl group-containing compound, at least one chlorine-containing organo-aluminum, boron, phosphorus or silicon compound, and at least one polybutadiene block copolymer. The catalyst component of the present invention has well-shaped particles, and a narrow particle size distribution; a polymerization reaction of olefins with the catalyst component produces well-shaped polymer particles with a high bulk density (BD) and an excellent comprehensive catalytic performance. The present invention also relates to a preparation method for said catalyst component and the application thereof, particularly in the homopolymerization and copolymerization of olefins such as ethylene, propylene, butene, hexene and octene. | ||
