  • Tridentate iminopyrrolyl nickel complexes and their use as catalysts for the reaction of polymerisation of ethylene to hyperbranched polyethylene
    Patent number: 11117913
    Abstract: The present invention relates to the preparation of novel nickel complexes containing iminopyrrolyl-type ligands, having the general molecular structure (I), and to their use as active catalysts in the polymerisation reaction of ethylene to hyperbranched polyethylene. The structure of the ligand precursor is such that it allows the occurrence of a cyclometallation reaction by the activation of a C—H bond, in the coordination reaction to the metal centre, generating a C,N,N?-tridentate complex.
    Type: Grant
