Title (EN) PROCATALYST COMPOSITIONS USEFUL FOR LOW COMONOMER INCORPORATION AND PROCESS FOR PREPARING THE SAME
(FR) COMPOSITIONS DE PROCATALYSEUR UTILES POUR DE FAIBLES NIVEAUX D'INCORPORATION DE COMONOMÈRES ET LEUR PROCÉDÉ DE PRÉPARATION
Abstract:
(EN) The present disclosure relates to novel procatalyst compositions including a titanium moiety, a magnesium halide support, a hydrocarbon solution in which the magnesium halide support is formed, and an electron donor modifier described herein. The present disclosure further relates to a one-pot process for preparing the novel procatalyst compositions, as well as use of the novel procatalyst compositions in solution processes for polymerization of ethylene and at least one addition polymerizable monomer to form a polymer composition.
(FR) La présente invention concerne de nouvelles compositions de procatalyseur comprenant une fraction de titane, un support d'halogénure de magnésium, une solution d'hydrocarbure dans laquelle le support d'halogénure de magnésium est formé, et un modificateur de donneur d'électrons. La présente invention concerne en outre un procédé monotope permettant de préparer les nouvelles compositions de procatalyseur, ainsi que l'utilisation des nouvelles compositions de procatalyseur dans des procédés en solution de polymérisation de l'éthylène et d'au moins un monomère polymérisable par addition pour former une composition polymère.
