| 摘要 |
The present invention relates to a method of polymerizing olefin containing the step of pre-polymerization. More precisely, according to the method of the present invention, the reaction speed and temperature are regulated for pre-polymerization of a catalyst and then the pre-polymerized catalyst is added for the polymerization of propylene. Propylene having an improved molecular weight distribution, hydrogen reactivity and tacticity is produced.
