An olefin polymerization catalyst system and method of making it are disclosed. The catalyst system comprises an activator and an organometallic complex. The complex comprises a Group 3 to 10 transition or lanthanide metal, M, and at least one anionic 1,3-diboretanyl ligand that is bonded to M. Molecular modeling results indicate that catalysts from organometallic complexes that incorporate anionic 1,3-diboretanyl ligands will rival the performance of traditional metallocenes.
L'invention porte sur un système de catalyseurs de polymérisation d'oléfines et son procédé d'obtention. Ledit système comporte un activateur et un complexe organométallique. Ledit complexe comprend un groupe de métaux de transition 3 à 10 ou de lanthanides et au moins un ligand anionique de 1,3-diborétanyle fixé à M. Le résultat d'une modélisation moléculaire indique que les catalyseurs de complexes organométalliques incluant des ligands anioniques de 1,3-diborétanyle peuvent rivaliser avec les performances des métallocènes traditionnels.
