| abstract |
More particularly, the present invention relates to a process for producing polypropylene, which comprises preparing a polypropylene by using prepolymerization using a metallocene supported catalyst, thereby securing the process stability through the uniformity of the morphology and the reduction of the derivative The present invention also provides a process for producing polypropylene which is capable of quantitatively controlling a supported catalyst to easily control pre-polymerization conditions and has a uniform particle size or distribution with respect to the finally obtained polymer. |
