The present invention relates to a catalyst for ethylene polymerization and copolymerization and a method for preparing the same, and more particularly, to a magnesium solution by contacting a magnesium halide compound with an alcohol, and to reacting a silicon compound having a phosphorus compound with an alkoxy group, The present invention relates to a solid complex titanium catalyst for ethylene polymerization and copolymerization prepared by reacting a mixture of a titanium compound and a silicon compound, and a method for producing the same. The catalyst of the present invention is highly active, and (co) polymers prepared using the catalyst of the present invention have the advantages of high apparent density and narrow molecular weight distribution. |
