摘要：在此提供一種製造烯烴聚合催化劑用的球形支撐物之方法，更特定來說，係提供一種製備烯烴聚合催化劑用的球形支撐物之方法，其包含在有一可起始反應的添加物存在下，讓鎂金屬與一醇類反應，其特徵為以鹵化的氮化物作為可起始反應的添加物，以獲得一球形二烷氧基鎂支撐物。由上述方法所獲得的該烯烴聚合催化劑用的球形支撐物為具有一平滑表面的球形顆粒，其顆粒大小分布均一，並具有0.25克/立方公分或更大的總體密度，使其適合用來製備一種可符合商用烯烴聚合反應所要求顆粒性質的催化劑，包括，例如漿聚合、大量聚合、氣相聚合等類似的反應。 Provided is a method for preparing a support for olefin polymerization catalysts used in polyolefin preparation processes. Particularly, provided is a novel method for preparing a support for olefin polymerization catalysts comprising the reaction of metal magnesium with an alcohol in the presence of an additive for initiating the reaction, characterized in that halogenated nitrogen compound is used as the additive for initiating the reaction, resulting in a spherical dialkoxy magnesium support. The spherical support for olefin polymerization catalysts obtained from the method of the present invention has a spherical particle shape with a smooth surface, uniform particle size distribution and 0.25g/cc or more of a bulk density, which makes it suitable for preparing a catalyst that is enough to meet the particle properties required by commercial olefin polymerization processes including, for example slurry polymerization, bulk polymerization, gas polymerization and the like. 【創作特點】本發明目的在於解決上述技藝中的問題，因此提供一種方法，其係用來製備烯烴聚合催化劑用的球形支撐物，其中該支撐物有一球形顆粒形狀，其有一均勻平滑表面及均一的顆粒大小分布，使得其適合用來製備一種催化劑，其係可滿足商用烯烴聚合製程(例如，漿式聚合、大量聚合、氣相聚合等)規格所要求之顆粒性質。
