METHOD OF MAKING MIXED ZIEGLER-NATTA/METALLOCENE CATALYSTS |
| 摘要 |
Methods of making mixed Ziegler-Natta/metallocene catalysts are disclosed. T he methods include slurrying a dehydrated support in a hydrocarbon solvent, adding a dialkylmagnesium compound, then adding a non-metallocene group 4 or 5 metal compound, followed by adding a metallocene, an alumoxane, and optional ly an aklyl aluminum compound and an electron donor compound, followed by dryin g the product. The alumoxane is added in an aromatic solvent.
