Catalyst systems comprising activator, polymerization processes using same, and products made therefrom

Abstract

This invention relates to a polymerization catalyst system comprising group 8 or 9 containing non-coordinating anion activator, a polymerization catalyst compound, optional support, and optional scavenger. Preferably, the activator comprises a compound represented by the formula: H(L)M where M is a group 8 or 9 metal, s is 0 or 1, m 1, 2, 3, or 4, each L ligand is independently C≡O, NR, PR, where each R, independently is halogen, haloalkyl, or haloaryl) or optionally two or more L ligands may together form a multiply-valent ligand complex. Further, this invention relates to anon-coordinating anion activator represented by the formula: [Z][HLM], where M, s, m, L, are as defined above, d is 1, 2, or 3 and Z is (L'-H) or a reducible Lewis acid; L′ is a neutral Lewis base; H is hydrogen, and (L′-H) is a Bronsted acid. This invention also relates to a process for making a polymeric product comprising contacting a C2-C40 alpha-olefin feed with the polymerization catalyst system to obtain a polymerization reaction mixture; and obtaining a polymer product from the polymerization reaction mixture.
