PROCESS FOR POLYMERIZING OLEFINS |
摘要 |
<p>A process for polymerizing or copolymerizing an alpha -olefin in the presence of a catalyst composed of (A)' a transition metal catalyst component resulting from supporting a halogen-containing transition metal compound on spray-dried solid spherical particles of a magnesium compound and (B)' an organometallic compound of a metal of Groups I to III of the periodic table, wherein the transition metal catalyst component (A)' is a catalyst component (A) prepared by supporting the halogen-containing transition metal compound on solid spherical particles having a specific surface area of at least 20 m2/g and an average particle diameter of 5 to 300 mu obtained by spray-drying a suspension of an oxygen-containing, halogen-free magnesium compound having an average particle diameter of 0.01 to 20 mu , and a catalyst composition for use therein.</p> |
