Catalyst component for ethylene polymerization and catalyst |
| abstract |
The invention provides a titanium-containing solid catalyst component for ethylene polymerization and a catalyst system composed of the titanium-containing solid catalyst component. A magnesium halide is dissolved in an organic epoxy compound and an organic phosphorus compound; the solution is added with an electron donor to form a uniform solution; and the solution reacts with a mixture of a transition metal titanium halide or its derivative, and a halohydrocarbon as an accelerator to produce the titanium-containing solid catalyst component. The catalyst system composed of the titanium-containing solid catalyst component is used for ethylene polymerization or copolymerization and has the characteristics of high activity, high bulk density and good catalyst hydrogen regulation sensitivity. |
