Abstract
The present invention relates to a method for preparing a solid titanium catalyst for olefin polymerization. The method for preparing a solid titanium catalyst for olefin polymerization according to the present invention comprises: preparing a magnesium compound solution by dissolving magnesium halide compound in a solvent mixture of cyclic ether and one or more of alcohol; preparing a carrier by adding titanium halide compound to said magnesium compound solution, then elevating the temperature of the solution and aging the solution to precipitate particles, and then adding titanium halide compound thereto for further reaction; preparing a catalyst by reacting said carrier with titanium compound and electron donor; and washing said catalyst with halogenated saturated hydrocarbon. According to the method of the present invention, a catalyst having high activity can be obtained and polyolefin produced by using the catalyst prepared by the method of the present invention has high stereoregularity, relatively easily compared with the conventional method.
