    摘要: A single-site olefin polymerization catalyst and method of making it are disclosed. The catalyst comprises an activator and an organometallic complex. The complex comprises a Group 3 to 10 transition or lanthanide metal, M, and at least one chelating N-oxide ligand that is bonded to M. Molecular modeling results indicate that single-site catalysts based on certain chelating N-oxide ligands (e.g., 2-hydroxypyridine) will rival the performance of catalysts based on cyclopentadienyl and substituted cyclopentadienyl ligands.
