CA 2300841

Catalyst systems useful for the polymerisation of 1-olefins are disclosed, which contain nitrogen-containing transition metal compounds comprising the skeletal unit depicted in Formula (B), wherein M is Fe[II], Fe[III], Ru[II], Ru[III] or Ru[IV]; X represents an atom or group covalently or ionically bonded to the transition metal M; T is the oxidation state of the transition metal M and b is the valency of the atom or group X; R1, R2, R3, R4 and R6 are independently selected from hydrogen, halogen, hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl; R5 and R7 are independently selected from hydrogen, halogen, hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl.

L'invention concerne des catalyseurs de polymérisation utiles pour la polymérisation des 1-oléfines. Ces catalyseurs comprennent des composés à base de métaux de transition contenant de l'azote et comportent l'unité squelette de formule (B), dans laquelle M est Fe[II], Fe[III], Ru[II], Ru[III] ou Ru[IV]; X représente un atome ou un groupe lié de manière covalente ou ionique au métal de transition M; T est l'état d'oxydation du métal de transition M et b est la valence de l'atome ou du groupe X; R<1>, R<2>, R<3>, R<4> et R<6> sont choisis indépendamment dans le groupe comprenant hydrogène, halogène, hydrocarbyle, hydrocarbyle substitué, hétéro-hydrocarbyle ou hétéro-hydrocarbyle substitué; R<5> et R<7> sont choisis indépendamment dans le groupe comprenant hydrogène, halogène, hydrocarbyle, hydrocarbyle substitué, hétéro-hydrocarbyle ou hétéro-hydrocarbyle substitué.
