A method for preparing high activity olefin polymerization catalyst |
| abstract |
The present invention relates to a process for preparing a highly active olefin polymerization catalyst which is easy to produce, can reduce complex steps and can be produced at a low temperature, comprising the steps of: (a) adding a magnesium halide to an alcohol solvent; (b) precipitating a solution obtained from (a) in a solution of an organic solvent containing an organic compound of a group III element; (c) adding a titanium compound to the mixture obtained from (b) to obtain a catalyst; (d) treating the catalyst obtained in (c) with an organoaluminum compound at a temperature in the range of 0 to 60 ° C for 2 to 5 hours, wherein the molar ratio of aluminum to titanium (Al / Ti) . |
