and a second catalyst compound that is a bridged or unbridged metallocene. M is a group 4 metal. X.sup.1 and X.sup.2 are independently a univalent C1-C20 hydrocarbyl, C1-C20 substituted hydrocarbyl, a heteroatom or a heteroatom-containing group, or X.sup.1 and X.sup.2 join together to form a C4-C62 cyclic or polycyclic ring structure. R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, and R.sup.10 is independently hydrogen, C1-C40 hydrocarbyl, C1-C40 substituted hydrocarbyl, a heteroatom or a heteroatom-containing group, or two or more of R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7, R.sup.8, R.sup.9, or R.sup.10 are joined together to form a C4-C62 cyclic or polycyclic ring structure, or a combination thereof. Q is a neutral donor group. Methods of polymerizing with the catalyst system to produce polyolefin polymers are also disclosed.

Provided in this disclosure are organometallic complexes that contain i) a metal atom selected from Hf and Zr; 2) a phosphinimine ligand; 3) an amido-ether ligand and at least one other ancillary ligand. The use of such a complex, in combination with an activator, as an olefin polymerization catalyst is demonstrated. The catalysts are effective for the copolymerization of ethylene with an alpha olefin (such as 1-butene, 1-hexene, or 1-octene) and enable the production of high molecular weight copolymers (Mw greater than 25,000) with good comonomer incorporation at high productivity.

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.sub.s(L).sub.mM 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 CO, NR.sub.3, PR.sub.3, 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.sub.d].sup.+[H.sub.sL.sub.mM].sup.d, 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.
