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. |

1. A method of preparation of a spherical support for an olefin polymerization catalyst, comprising:
i) preparing MgX(I), where X is halogen atom, and (I) refers to an oxidation state number by reacting a halogenated nitrogen compound and magnesium metal at a same ratio in equivalent weight; and ii) reacting magnesium metal and alcohol in the presence of the MgX obtained from the step i), wherein the halogenated nitrogen compound is at least one selected from the group consisting of the following structures (1), (2), (3), and (4): (1) N-halide succinimides where X is a halogen atom, and R1, R2, R3 and R4 are independently hydrogen or C1-C12 alkyl or C6-C20 aryl, (2) trihaloisocyanuric acids where X is a halogen atom, (3) N-halophthalimides where X is a halogen atom, and R1, R2, R3 or R4 are independently hydrogen, or C1-C12 alkyl or C6-C20 aryl, and (4) hydantoins where X is a halogen atom, and R1 and R2 are independently hydrogen, or C1-C12 alkyl or C6-C20 aryl. |
