Process for preparing polyolefins |
| abstract |
According to the present invention, there is provided a process for preparing polyolefins which comprises polymerizing or copolymerizing olefins using as catalyst a solid component containing a titanium compound and/or a vanadium compound, and an organoaluminum compound and/or an organozinc compound, said solid component being obtained by copulverizing (1) a magnesium halide and/or a manganese halide, (2) an aluminum oxyhalide and (3) a titanium compound and/or a vanadium compound. |
