Abstract
A process for polymerizing olefins is disclosed. The process uses an organometallic complex with at least one non-bridged indenoindolyl ligand bonded to M. The substituent on the indole nitrogen contains an atom selected from the group consisting of S, O, P, and N. Polyolefins from the process have unexpectedly high molecular weight compared with polyolefins made using similar supported indenoindolyl complexes.
Claims16
A process which comprises polymerizing an olefin in the presence of an activator and an organometallic complex, wherein the organometallic complex comprises a Group 3 to 10 transition metal, M, and at least one non-bridged indenoindolyl ligand that is bonded to M wherein the indenoindolyl ligand has a structure selected from the group consisting of:
- in which R1 is a C2-C30 radical containing an atom selected from the group consisting of S, O, P, and N;
- and each R2 is independently selected from the group consisting of C1-C30 hydrocarbyl, H, F, Cl, and Br.
