    • Provided is a preparation method of a catalyst for ethylene (co)polymerization, comprising the following steps: (1) preparing a magnesium compound solution by contact-reacting a halogenated magnesium compound with a mixed solvent of cyclic ether and at least one alcohol; (2) reacting the resulted magnesium compound solution from the above step (1) with a silicon compound having at least one alkoxy group; (3) preparing a support by adding a titanium compound to the resulted product from the step (2); and (4) reacting thus obtained support with a titanium compound and optionally a monoester compound, resulting in a catalyst. Catalysts prepared according to the present invention have a regulated particle shape, and their particle size can be easily adjusted. Therefore, with such catalyst, it is possible to produce polymers having high bulk density at high production yield.
    • 提供了一种乙烯(共)聚合催化剂的制备方法,包括以下步骤:(1)通过使卤代镁化合物与环醚和至少一种醇的混合溶剂接触反应来制备镁化合物溶液; (2)使所得到的上述步骤(1)的镁化合物溶液与具有至少一个烷氧基的硅化合物反应; (3)通过向步骤(2)得到的产物中加入钛化合物制备载体; 和(4)使由此获得的载体与钛化合物和任选的单酯化合物反应,得到催化剂。 根据本发明制备的催化剂具有调节的颗粒形状,并且其粒度可以容易地调节。 因此,通过这样的催化剂,能够以高的产率制造高堆积密度的聚合物。
