Process for preparing polyolefins |
| 摘要 |
According to the present invention, there is provided a process for preparing polyolefins by polymerizing or copolymerizing olefins in the presence of a catalyst consisting of a solid component and an organometallic compound component, characterized in that said solid component is obtained by copulverizing 1. A MAGNESIUM HALIDE, 2. A COMPOUND REPRESENTED BY THE GENERAL FORMULA Al(OR)mX3-m wherein R is alkyl and/or aralkyl having 1 to 20 carbon atoms and may be the same or different, X is halogen and O<m</=3, 3. A TETRAVALENT TITANIUM COMPOUND, AND 4. A TRIVALENT TITANIUM COMPOUND AND IN THAT SAID ORGANOMETALLIC COMPOUND COMPONENT IS A MIXTURE OF 5. A TRIALKYLALUMINUM AND 6. A COMPOUND REPRESENTED BY THE GENERAL FORMULA AlR'nX3-n wherein R' is alkyl having 1 to 10 carbon atoms and may be the same or different, X is halogen and O<n<3.
