PROPYLENE POLYMER, METHOD FOR PRODUCTION OF THE PROPYLENE POLYMER, PROPYLENE POLYMER COMPOSITION, AND MOLDED ARTICLE MANUFACTURED FROM THE COMPOSITION |
摘要 |
<p>Disclosed is a production method of polypropylene having high MFR value and excellent product qualities with high productivity. The method enables to produce a propylene polymer by a gas phase process where the reaction heat is removed mainly by the heat of vaporization of liquefied propylene. The method is characterized by using a solid catalyst component (A) which is prepared by contacting components (A1), (A2) and (A3) shown below. Further disclosed are: a propylene polymer produced by the method; a propylene polymer composition; and a molded body of the composition. Component (A1) : a solid component containing titanium, magnesium and a halogen as essential components. Component (A2): a vinyl silane compound. Component (A3): an organosilicon compound having an alkoxy group (A3a) and/or a compound having at least two ether bonds (A3b).</p> |
