Process for preparing a supported catalyst system for olefin polymerization, the catalyst system and its use
摘要：
The invention refers to a process for preparing a supported catalyst system for the polymerization of olefins comprising at least one active catalyst component on a support, the process comprisingA) impregnating a dry porous support component with a mixture comprising at least one precatalyst, at least one cocatalyst, and a first solvent, such that the total volume of the mixture is from 0.8 to 2.0 times the total pore volume of the support component, and B) thereafter, adding a second solvent in an amount of more than 1.5 times the total pore volume of the support component. The invention refers further to a catalyst system made by this process and the use of this catalyst system for polymerization or copolymerization of olefins.
摘要（中）：

本发明涉及一种制备负载型催化剂体系的方法，所述催化剂体系包括在载体上包含至少一种活性催化剂组分的烯烃聚合，所述方法包括：A）至少将含有至少一种预催化剂的混合物浸渍在干多孔载体组分中，至少 一种助催化剂和第一溶剂，使得混合物的总体积为载体组分的总孔体积的0.8-2.0倍，B）然后，加入第二种溶剂的总量的1.5倍以上 载体组分的孔体积。 本发明还涉及通过该方法制备的催化剂体系和该催化剂体系用于烯烃聚合或共聚的用途。
