The present invention is directed to certain storage stable non-ionic late transition metal chelate compounds, methods of forming same, and the use of said compounds as catalysts for the polymerization of olefins and functionalized olefins in the presence of said chelate compounds. The chelates are bidentate compounds which are free of electron withdrawing groups, have sterically bulky groups proximate to the chelated metal atom and is free of associated ligand.
La présente invention se rapporte à certains composés chélates de métaux de transition tardive, non ioniques et stables vis à vis du stockage. Elle se rapporte également à des procédés de fabrication de ces composés et à leur utilisation en tant que catalyseurs pour la polymérisation d'oléfines et d'oléfines fonctionnalisées en présence desdits composés chélates. Ces chélates sont des composés bidentés qui ne comportent pas de groupe de retrait d'électrons, qui comportent des groupes stériquement encombrants à proximité de l'atome métallique chélaté et qui ne possèdent pas de ligand associé.
