Title
(EN) PROCESS SELECTIVELY POLYMERIZING ETHYLENE AND CATALYST THEREFOR
(FR) PROCÉDÉ DE POLYMÉRISATION SÉLECTIVE DE L'ÉTHYLÈNE, ET CATALYSEUR À CET EFFET
Abstract
(EN)
The present invention generally relates to a process that selectively polymerizes ethylene in the presence of an alpha-olefin, and a precatalyst and catalyst useful in such processes.
(FR)
La présente invention concerne, d'une façon générale, un procédé permettant la polymérisation de l'éthylène en présence d'une α-oléfine, et un pré-catalyseur ainsi qu'un catalyseur convenant à de tels procédés.
