Title (EN) TRANSITION METAL COMPLEXES, CATALYST COMPOSITIONS CONTAINING THE SAME, AND OLEFIN POLYMERIZATION USING THE CATALYST COMPOSITIONS
(FR) COMPLEXES DE MÉTAUX DE TRANSITION, COMPOSITIONS DE CATALYSEURS LES COMPRENANT ET POLYMÉRISATION D’OLÉFINES UTILISANT LES COMPOSITIONS DE CATALYSEURS
Abstract: front page image
(EN)Provided are a novel transition metal complex where a monocyclopentadienyl ligand to which an amido or alcoxy group is introduced is coordinated, a method of synthesizing the same, and olefin polymerization using the transition metal complex . Compared to a conventional transition metal complex having a silicon bridge and an oxido ligand, the transition metal complex has a phenylene bridge, so that a monomer easily approaches the transition metal complex in terms of structure and a pentagon ring structure of the transition metal complex is stably maintained. The catalyst composition including the transition metal complex is used to synthesize a polyolefin copolymer having a very low density less than 0.910 g/cc.
(FR)La présente invention concerne un nouveau complexe de métal de transition où un ligand monocyclopentadiényle, dans lequel on introduit un groupe amido ou alcoxy, est coordonné, un procédé de synthèse de celui-ci et une polymérisation des oléfines qui utilise le complexe de métal de transition. Comparativement à un complexe de métal de transition traditionnel qui possède un pont silicium et un ligand oxydo, le complexe de métal de transition possède un pont phénylène, de sorte qu'un monomère approche facilement le complexe de métal de transition relativement à la structure, et une structure de noyau en forme de pentagone du complexe de métal de transition est maintenue stable. La composition de catalyseur qui comprend le complexe de métal de transition est utilisée pour synthétiser un copolymère de polyoléfine qui possède une très basse densité inférieure à 0,910 g/cc.
