OLEFIN POLYMERIZATION CATALYST, PROCESS FOR PRODUCING OLEFIN POLYMER, POLYPROPYLENE RESIN COMPOSITION AND ARTICLE COMPRISING THE SAME |
摘要 |
An olefin polymerization catalyst is obtained by bringing the following components (A), (B) and (C) into contact with one another: (A) a solid catalyst component for olefin polymerization containing a titanium atom, a magnesium atom and a halogen atom; (B) an organoaluminum compound; and (C) a triether represented by formula (I). An olefin polymerization solid catalyst can be provided having a sufficiently high polymerization activity and an ability to produce an olefin polymer with a low content of low-molecular weight components and amorphous components. |
