Abrégé
(EN)
The present disclosure provides catalyst compounds including a nonsymmetric bridged amine bis(phenolate), catalyst systems including such, and uses thereof. Catalyst compounds, catalyst systems, and processes of the present disclosure can provide high comonomer content and high molecular weight polymers having narrow Mw/Mn values, contributing to good processability for the polymer itself and for the polymer used in a composition.
(FR)
La présente invention concerne des composés catalytiques comprenant un bis(phénolate) d'amine ponté non symétrique, des systèmes catalytiques comprenant de tels composés, et leurs utilisations. Les composés catalytiques, les systèmes catalytiques et les procédés de la présente invention permettent d'obtenir une teneur élevée en comonomère et des polymères de poids moléculaire élevé ayant des valeurs Mw/Mn étroites, contribuant à une bonne aptitude au traitement pour le polymère lui-même et pour le polymère utilisé dans une composition.
