Title (EN) HIGH TEMPERATURE POLYETHYLENE SOLUTION POLYMERIZATION PROCESS
(FR) PROCÉDÉ DE POLYMÉRISATION DE SOLUTION DE POLYÉTHYLÈNE HAUTE TEMPÉRATURE
Abstract:
(EN) Metal complexes of polyvalent aryloxyethers appropriately substituted with sterically bulky substituents possess enhanced solubility in aliphatic and cycloaliphatic hydrocarbons and/or when employed as catalyst components for the polymerization of ethylene/ α-olefin copolymers, produce products having reduced I10/I2 values.
(FR) Aux fins de l'invention, certains complexes métalliques d'aryloxyéthers polyvalents substitués de façon appropriée avec des substituants à encombrement stérique offrent une solubilité améliorée dans des hydrocarbures aliphatiques et cycloaliphatiques et/ou en utilisation comme composants catalyseurs pour la polymérisation de copolymères d'éthylène/ α-oléfine, ce qui permet d'élaborer des produits à valeurs I10/I2 réduites.
