Patent ID: 8058372

Claim:
A process to produce homopolymers or copolymers of oligomers produced by contacting monomers with a catalyst system comprising an activator and a transition metal catalyst compound, wherein the transition metal catalyst compound is selected from the group consisting of compounds represented by the formula: wherein each M is, independently, nickel, cobalt, iron or manganese; N is nitrogen; C is carbon; each X is, independently, an anionic monodentate ligand, or both X groups together may form a bidentate dianionic ligand; each Râ€² is, independently, a hydrogen, a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, or a substituted halocarbyl; independently, two Râ€² groups on the same carbon may join to form a cyclic or polycyclic ring structure; when y is 2, 3, or 4, two or more Râ€² groups on adjacent carbon atoms may join to form a cyclic or polycyclic ring structure; each y is, independently, 1, 2, 3 or 4; each R1 and R3 is, independently, a hydrogen, hydrocarbyl or halocarbyl; each R2 and R4 is, independently, a C3 to C50 hydrocarbyl or a C3 to C50 halocarbyl; each R5 is, independently, hydrogen, a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, or a substituted halocarbyl; optionally R5 may be bonded to M through the heteroatom of a substituted hydrocarbyl, or a substituted halocarbyl; Lâ€² is a neutral ligand bonded to M; and w is 0 or 1; said process comprising using said oligomers in a Ziegler-Natta type polymerization or a metallocene catalyzed polymerization.
