Title of Invention

" A SUPPORT6ED CATALYST SYSTEM FOR OLEFIN POLYMERIZATION."

Abstract A PHOSPHINIMINE CATALYST FOR LOEFIN POLYMERIZATION IS SUPPORTED ON A DIRECTLY FLUORIDED METAL OXIDE WITH AN ALUMINOXANE, THIS CATALYS IS HIGHLY ACTIVE FOIR OLEFIN POLYMERIZATION IS COMPARISON TO PRIOR ART CATALYSTS WHICH USE NON FLUORIDED METAL OXIDE SUPPORTS. THE DIR4ECTLY FLUORIDEDMETAL OXIDE MAY BE CONVENIENTLY PROPARED BY CONTACTING THE PRECURSOR METAL OXIDE WITH AMIMPLE ALKALI METAL SALT (SUCH AS NAF) IN AN AQUEOUS SLURRY.
