METHOD FOR CONTROLLING SIZE OF SPHERICAL CARRIER FOR OLEFIN POLYMERIZATION CATALYST

摘要

Provided is a method for controlling the size of a dialkoxy magnesium carrier used in preparation of an olefin polymerization catalyst. Specifically, provided is a method for controlling the size of a dialkoxy magnesium carrier for preparation of an olefin polymerization catalyst which includes preparation of a dialkoxy magnesium carrier by reacting metal magnesium with an alcohol in the presence of an reaction initiator such as magnesium halide or nitrogen halide, by adding the metal magnesium and the alcohol to the reaction in divided portion(s) of 1-3.
