Title
(EN) HIGH EFFICIENCY SOLUTION POLYMERIZATION PROCESS
(FR) PROCÉDÉ DE POLYMÉRISATION EN SOLUTION À RENDEMENT ÉLEVÉ
Abstract
(EN)
A catalyst composition comprising a zirconium complex of a polyvalent aryloxyether and an alumoxane, polymerization processes employing the same, especially the continuous, solution polymerization of ethylene and one or more C3-30 olefins or diolefins to prepare copolymers having reduced cocatalyst by-product content, are disclosed.
(FR)
L'invention concerne une composition catalytique comprenant un complexe de zirconium d'un aryloxyéther polyvalent et un alumoxane, ainsi que des procédés de polymérisation utilisant cette composition catalytique, notamment la polymérisation continue en solution d'éthylène et d'une ou de plusieurs oléfines ou dioléfines C3-30 pour préparer des copolymères ayant une teneur réduite en sous-produit cocatalyseur.
