| titleOfInvention | Catalyst component for ethylene polymerization and its preparation method and catalyst for ethylene polymerization |
| abstract | The invention relates to the technical field of catalysts for olefin polymerization, and provides a catalyst component for ethylene polymerization, a preparation method thereof and a catalyst for ethylene polymerization. The catalyst component includes the reaction product of the following components: (1) magnesium compound; (2) organic epoxy compound; (3) organosilicon compound; (4) titanium-containing compound; (5) aromatic alkoxy ester compound ; Wherein, the structure of the aromatic alkoxy ester compound is shown in general formula (I). The method comprises: contacting a magnesium compound, an organic epoxy compound, and an organosilicon compound to react to form a uniform solution; after cooling down to -40-10°C, contacting it with a titanium-containing compound to obtain a mixture; combining the mixture with The aromatic alkoxy ester compounds are contacted, and the temperature is raised slowly to react to obtain the catalyst component. The catalyst component particle shape of the invention is good, the catalytic activity is high, the hydrogen adjustment sensitivity is good, and the polymer obtained by polymerization has a high packing density. |
