| titleOfInvention | METHOD FOR PRODUCING Catalyst COMPOSITION for Polymerization of High Density PolyETHYLENE |
| abstract | The present invention provides a method for producing a catalyst for high-density polyethylene polymerization, a catalyst for high-density polyethylene polymerization, and a method for producing polyethylene using the catalyst. (A) preparing a magnesium compound solution by dissolving a magnesium compound in a solvent containing a first hydrocarbon solvent having 5 to 25 carbon atoms and an alcohol; (B) reacting the magnesium compound solution with a dialkoxyphenyl; And (C) reacting the product of step (B) with a transition metal compound in the presence of a second hydrocarbon solvent having 6 to 25 carbon atoms. The catalyst of the present invention includes a magnesium compound, a transition metal compound, and a dialkoxyphenyl. The catalyst has a constant shape and has a small particle size and a narrow particle size distribution. The ethylene polymer obtained after the polymerization is also highly active and has a narrow molecular weight distribution and a low generation of fine particles. |
