METHOD FOR CONTROLLING SIZE OF SPHERICAL CARRIER FOR OLEFIN POLYMERIZATION CATALYST

摘要

The present invention relates to a method for controlling the size of a dialkoxy magnesium carrier used in the manufacture of an olefin polymerization catalyst. More specifically, the present invention relates to a method for controlling the size of a dialkoxy magnesium carrier for an olefin polymerization catalyst by injecting metallic magnesium and alcohol in 1-3 times and reacting them, when the dialkoxy magnesium carrier is prepared by reacting the metallic magnesium with alcohol in the presence of a magnesium halide or nitrogen-halogen compound as a reaction initiator.
