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.

摘要: A medium pressure process for the solution polymerization of ethylene at a temperature of from 80° C. to 250° C. in the presence of a catalyst system comprising (1) a catalyst component which is a group 4 metal complex having a delocalized, cyclic, pi-bonded ligand, a (defined, specific) heteroligand and one or two activatable ligands; and (2) an ionic activator which does not contain an active proton. The catalyst component is unbridged and easily synthesized. It is highly active in solution polymerization when properly activated (but is not active when used in combination with an alumoxane). Preferred catalyst systems contain an unbridged monocyclopentadienyl titanium (IV) complex and triphenylcarbenium tetrakis (pentafluorophenyl) borate.
