SUPPORTED PHOSPHINIMINE POLYMERIZATION CATALYST |
摘要 |
A phosphinimine catalyst for olefin polymerization is supported on a directly fluorided metal oxide with an aluminoxane. This catalyst is highly active for olefin polymerization in comparison to prior art catalysts which use non-fluorided metal oxide supports. The directly fluorided metal oxide may be conveniently prepared by contacting the precursor metal oxide with a simple alkali metal salt (such as NaF) in an aqueous slurry.
