Patent

CA 2542747

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.

L'invention concerne un procédé de polymérisation d'oléfines. Le procédé décrit dans cette invention consiste à utiliser un complexe organométallique présentant au moins un ligand indénoindolyle non ponté relié à M. Le substituant sur l'azote indole contient un atome choisi dans le groupe comprenant S, O, P, et N. Les polyoléfines obtenues grâce au procédé susmentionné présentent un poids moléculaire étonnamment élevé en comparaison aux polyoléfines obtenues au moyen de complexes indénoindolyles supportés.
