    摘要: The invention relates to transition metal complexes comprising a metal of group 3, 4, or 6 of the Periodic Table of the Elements and one, or two mono-anionic triazole ligands It has been found that these transition metal complexes which comprise at least one triazole fragment having a substituent with an unsaturated fragment are suitable as precatalysts for the polymerization of olefins. In these complexes one carbon atom of the unsaturated fragment is bound directly or via a bridge to a triazole group and the other carbon atom is bound to the transition metal. The complexes are useful as catalysts for olefin polymerization, a catalyst system comprising these complexes and a process for the polymerization of olefins under the use of the catalyst system.

    摘要: Catalysts useful for polymerizing olefins are disclosed. The catalysts comprise an activator and a bridged cyclopentadienyl complex that incorporates a monoanionic hydroxylamido or hydrazido ligand fragment. Suitable complexes have the structure: wherein M is a Group 4 metal; Z is a divalent linking group; X is N or O; each of R1 and R2 is independently C1-C4 alkyl or C6-C10 aryl; R1 and R2 can be joined together; n is 0 when X is O, and n is 1 when X is N; each Y is independently halide, alkyl, dialkylamido, aryl, or aralkyl. A modeling approach is used to identify particular valuable complexes, each of which incorporates a readily synthesized cyclopentadienyl precursor.

    摘要: Catalysts useful for polymerizing olefins are disclosed. The catalysts comprise an activator and a Group 4 transition metal complex which comprises at least one monoanionic R1N—XR2 ligand, where X is O or S, and each of R1 and R2 is independently alkyl, aryl, arylalkyl, alkylaryl, or trialkylsilyl. The complexes are readily made from R1NH—XR2 precursors and are often useful as catalyst components without further purification. The catalysts have good activities, incorporate comonomers well, and provide polymers with high molecular weight.
