The present invention is directed to certain novel late transition metal salicylaldimine chelates and, further, to novel bidentate ligand compounds of substituted salicylaldimine, and their utility as polymerization catalysts alone or in combination with adjunct agent and/or Lewis base in processes of polymerizing olefin monomers and copolymerizing olefin monomers with functionalized olefin monomers.
L'invention se rapporte à certains nouveaux chélates salicylaldimine de métaux de transition tardive et, en outre, à de nouveaux composés ligands bidentés de salicylaldimine substituée. L'invention concerne également leur utilité en tant que catalyseurs de polymérisation, seuls ou en combinaison avec un agent auxiliaire et/ou une base de Lewis pour la polymérisation de monomères d'oléfine et la copolymérisation de monomères d'oléfine avec des monomères d'oléfine fonctionnalisés.
