| titleOfInvention | Catalyst component for ethylene polymerization and catalyst |
| abstract | The invention discloses a catalyst component for ethylene polymerization, which is prepared by dissolving magnesium halide in an organic epoxy compound and an organic phosphorous compound to form uniform solution, adding a halohydrin compound and an alcohol, and reacting with a titanium compound in the presence of an active hydrogen-free organic silicon compound auxiliary precipitator. In the invention, because of the use of the active hydrogen-free organic silicon compound as the auxiliary precipitator and the inter-molecular construction function of halohydrin, the catalyst particles can precipitate easily in the preparation process of the catalyst component without using a large amount of titanium tetrachloride to promote the precipitation of the precipitate nor using titanium tetrachloride to treat the precipitate for many times, so the consumption of titanium tetrachloride is reduced greatly. Meanwhile, the addition of the organic silicon compound helps to improve the activity and particle form of the catalyst, and when used for ethylene polymerization, the catalyst shows high polymerization activity and high hydrogen adjustment sensitivity. |
