Catalyst composition, method of making same and its use in olefin polymerization

Abstract

A composition of matter comprising a compound having the general formula: [CpM(ArF)Y]pwhereinCp is a substituted or unsubstituted cyclopentadienyl ligand or cyclopentadienyl-type bulky ligand characterized by one or more open, acylic or fused ring systems comprised of atoms selected from Groups 13-16 of the Periodic Table of Elements and wherein the ligands can include a heteroatom;M is a metal selected from Groups 3-9 of the Periodic Table of Elements;ArF is a fluorinated aryl group;Y is a hydrocarbyl group that can contain a heteroatom; and p is 1 or 2. The invention also contemplates a method of producing the compound and its use in the oligomerization and polymerization of alpha olefins.
