Catalyst compositions containing transition metal complexes with thiolate ligands

摘要

The present invention discloses catalyst compositions employing transition metal complexes with a thiolate ligand. Methods for making these transition metal complexes and for using such compounds in catalyst compositions for the polymerization of olefins also are provided.

主权项

1. A catalyst composition comprising an activator and a compound having the formula:wherein:
M1 is a transition metal; each R1A and R1B independently is a C1 to C18 hydrocarbyl or hydrocarbylsilyl group, wherein p and q independently are 1, 2, 3, or 4; D is O or NR1C, wherein R1C is hydrogen or a C1 to C18 hydrocarbyl group; each X0 independently is a neutral ligand, wherein a is 0, 1, or 2; each X1 independently is a monoanionic ligand, wherein b is 0, 1, 2, 3, or 4; X2 is a dianionic ligand, wherein c is 0 or 1; and an oxidation state of M1 is equal to (b+2c+2).
