Title
(EN) TRIDENTATE METAL CATALYST FOR OLEFIN POLYMERIZATION
(FR) CATALYSEUR MÉTALLIQUE TRIDENTATE POUR LA POLYMÉRISATION D'OLÉFINES
Abstract
(EN)
A process for the preparation of a tridentate transition metal catalyst components incorporating pyridinyl bis-amino or monoamino ligand structures which do not require π bonding of the transition metal through the use of cyclopentadienyl rings. The ligand structure incorporates a heteroatom group that involves nitrogen in one organogroup and either oxygen or nitrogen in another organogroup. The process of preparing the catalyst component involves the reaction of a bis-amino or oxyamino pyridenyl ligand compound with an organo transition metal compound involving a tetrabenzyl ligand or other functional group ligands linked to a transition metal such as titanium zirconium or hafnium.
(FR)
L'invention concerne un procédé de préparation de composants de catalyseur à base de métal de transition tridentate comprenant des structures de ligand pyridinyle bis-amino ou mono-amino ne nécessitant pas de liaison π du métal de transition par utilisation de cycles cyclopentadiényle. La structure de ligand comprend un groupement hétéroatome comprenant de l'azote dans un groupement organique et de l'oxygène ou de l'azote dans un autre groupement organique. Le procédé de préparation du composant de catalyseur comprend la réaction d'un composé ligand bis-amino ou oxyamino pyridényle avec un composé de métal de transition organique comprenant un ligand tétrabenzyle ou des ligands ayant d'autres groupements fonctionnels liés à un métal de transition tel que le titane, le zirconium ou l'hafnium.
