Title (EN) A POLYMERIZATION PROCESS FOR PRODUCING ETHYLENE BASED POLYMERS
(FR) PROCÉDÉ DE POLYMÉRISATION POUR PRODUIRE DES POLYMÈRES À BASE D'ÉTHYLÈNE
Abstract:
(EN) The instant invention provides a polymerization process for producing ethylene based polymers. In one embodiment, the instant invention provides a polymerization process for producing ethylene based polymers comprising: polymerizing ethylene with optionally one or more a- olefins in the presence of one or more first catalyst systems and optionally one or more second catalyst systems in a single reactor, wherein first catalyst system comprises; (a) one ore more procatalysts comprising a metal-ligand complex of formula (I):
(FR) La présente invention concerne un procédé de polymérisation destiné à produire des polymères à base d'éthylène. Dans un mode de réalisation, la présente invention concerne un procédé de polymérisation destiné à produire des polymères à base d'éthylène, comprenant : la polymérisation d'éthylène avec éventuellement une ou plusieurs a-oléfines en présence d'un ou de plusieurs premiers systèmes catalytiques et éventuellement d'un ou de plusieurs deuxièmes systèmes catalytiques dans un réacteur unique, le premier système catalytique comprenant : (a) un ou plusieurs procatalyseurs comprenant un complexe métal-ligand de formule (I) :
