Abstract
(EN)
This invention relates to a process for polymerizing ethylene comprising contacting ethylene and optional comonomers with a catalyst system comprising an activator and a transition metal compound represented by formula (I): wherein R1 and R2 are independently hydrogen or a group having up to 100 carbon atoms, Cp1 is a bulky ligand; Cp2 is a bulky ligand or a heteroatom optionally bound to a C1 to C50 hydrocarbyl group, n is the valence state of the transition metal, Tm is a Group 3 to 10 metal, and each X is independently an anionic leaving group.
(FR)
Cette invention concerne un procédé de polymérisation de l'éthylène. Il consiste à mettre en contact de l'éthylène et éventuellement des comonomères avec un système catalyseur renfermant un activateur et un composé métallique de transition représenté par la formule (I). Dans cette formule, R1 et R2 sont indépendamment hydrogène ou un groupe comptant jusqu'à 100 atomes de carbone, Cp1 est un ligand volumineux, Cp2 est un ligand volumineux ou un hétéroatome éventuellement lié à un groupe hydrocarbyle en C1-C50, n représente la valence du métal de transition, Tm est un métal de groupe 3 à 10 et chaque X est indépendamment un groupe anionique partant.
