    摘要: Provided is a method of preparation of a spherical support for an olefin polymerization catalyst. Specifically, provided is a method of preparation of a support which can be used in preparation of an olefin polymerization catalyst, wherein, MgX(I) (X=halogen atom) is prepared by reacting a reaction initiator, nitrogen halide, and magnesium metal, and then magnesium metal and alcohol are reacted in the presence of the MgX, thereby resulting a smooth-surfaced spherical dialkoxy magnesium support having a uniform particle size distribution.

    摘要: The present invention relates to a Ziegler-Natta catalyst for olefin polymerization and a method for polymerization of olefin using the same. Specifically, the invention relates to a Zeigler-Natta catalyst for olefin polymerization, which is produced by a method comprising the step of reacting a transition metal compound in which the transition metal having an oxidation number of 4 or more is selected from Groups IV, V or VI of the Periodic table and two or more aryloxy ligands are bound to the transition metal, with an organomagnesium compound, to reduce said transition metal compound to a reduced form in which the transition metal has an oxidation number of 3, and a method for polymerization of olefin using said catalyst.
