| titleOfInvention | Method for preparing solid catalyst for ethylene gas phase polymerization and method for ethylene polymerization or copolymerization using catalyst produced thereby |
| abstract | The present invention is a method for producing a solid catalyst for ethylene gas phase polymerization, wherein an oxide of a tetravalent titanium compound is reacted with an organomagnesium compound, followed by addition of an alkoxysilane compound during or after completion of the reaction. It is about. The present invention also relates to a method for producing an ethylene (co) polymer in a high yield in a gas phase step using a trialkylaluminum compound as a cocatalyst in the solid catalyst obtained by the above method. According to the present invention, the alkoxysilane-based compound is used as an electron donor material to control the catalytic activity in the preparation of a solid catalyst, so that agglomeration of the polymer due to a sudden rise in temperature in the reactor during the gas phase polymerization of ethylene does not occur. It is possible to stably produce polyethylene with high yield. |
