    • Provided is a process for polymerization and copolymerization of ethylene, specifically comprising carrying out polymerization or copolymerization ethylene in the presence of (a) a solid complex titanium catalyst which is produced by the process comprising: (i) preparing a magnesium compound solution by contacting a halogenated magnesium compound and an alcohol for allowing a reaction; (ii) reacting the resulted magnesium compound solution with an ester compound having at least one hydroxyl group and a silicon compound having at least one alkoxy group; (iii) reacting the resulted solution with a mixture of a titanium compound and a silicon compound to obtain a solid titanium catalyst component; (iv) washing the resulted solid titanium catalyst component with a halogenated saturated hydrocarbon compound; and (v) further reacting the washed solid titanium catalyst component with a titanium compound to obtain a solid complex titanium catalyst, and (b) an organometallic compound from Group II or III of Periodic table of elements. According to the present invention, it is possible to provide a process for polymerization or copolymerization of ethylene in which the catalyst activity is improved and a polymer of high bulk density is provided, with the use of a catalyst prepared by a simple process.
    • 提供了一种乙烯的聚合和共聚方法,特别包括在(a)固体络合物钛催化剂的存在下进行聚合或共聚乙烯,所述固体络合物钛催化剂通过以下方法制备,所述方法包括:(i)通过使 卤化镁化合物和用于允许反应的醇; (ii)使得到的镁化合物溶液与具有至少一个羟基的酯化合物和具有至少一个烷氧基的硅化合物反应; (iii)使所得溶液与钛化合物和硅化合物的混合物反应,得到固体钛催化剂组分; (iv)用卤化饱和烃化合物洗涤得到的固体钛催化剂组分; 和(v)使洗涤的固体钛催化剂组分与钛化合物进一步反应以获得固体络合物钛催化剂,和(b)元素周期表第II或III族的有机金属化合物。 根据本发明,通过使用通过简单的方法制备的催化剂,可以提供改进催化剂活性的乙烯的聚合或共聚方法和提供高堆积密度的聚合物。
