The present invention relates to a catalyst for polymerization and co-polymerization of ethylene. More particularly, the present invention relates to a solid titanium catalyst containing magnesium, wherein said catalyst is produced by preparing a magnesium solution by contact-reacting a halogenated magnesium compound with alcohol; reacting said solution with an ester compound having at least one hydroxy group, or a phosphorous compound and a silicon compound having alkoxy groups; producing a solid component with an adjusted particle morphology by adding a mixture of a titanium compound and a silicon compound; reacting the same with an aluminum compound; and then reacting the same with a titanium compound, or a titanium compound and a vanadium compound. As a result, the catalyst of the present invention has high catalytic activity with excellent catalyst morphology.
本发明涉及一种乙烯聚合和共聚合催化剂。更具体地说,本发明涉及一种含镁的固体钛催化剂,其中所述催化剂是通过以下方法制备的:将卤代镁化合物与醇接触反应制备镁溶液;将所述溶液与具有至少一个羟基的酯化合物或磷化合物和具有烷氧基的硅化合物反应;加入钛化合物和硅化合物的混合物,使其与铝化合物反应,然后与钛化合物或钛化合物和钒化合物反应,制得具有调整颗粒形态的固体组分。因此,本发明的催化剂具有很高的催化活性和优异的催化剂形态。
