Abstract

This invention relates to fluorinated alkoxy-imino metallic complexes and their use in catalyst systems for the polymerisation or oligomerisation of ethylene and alpha-olefins.

Claims

exact text as granted — not AI-modified
1 - 18 . (canceled) 
     
     
         19 . A method for forming the metallic complex of claim  12  comprising:
 providing the fluorinated alcohol-imine pro-ligand; and 
 complexing the fluorinated alcohol-imine pro-ligand with the metal salt or precursor of formula MX 4 . 
 
     
     
         20 . An active catalyst system comprising the metallic complex of claim  12  and an activating agent having an ionising action and optionally a cocatalyst. 
     
     
         21 . The active catalyst of  claim 20 , wherein the activating agent is aluminoxane or an activating support.
