Title (EN) OLEFIN POLYMERIZATION CATALYST
(FR) CATALYSEUR DE POLYMÉRISATION OLÉFINIQUE
Abstract:
(EN) A process for preparing a solid pre-catalyst component for use in olefinic polymerization includes dissolving a magnesium chloride in an alcohol and optionally adding water to form a first solution having a water content of about 0.5 mmol water per mol MgCl2 to about 100 mmol water per mol MgCl2; contacting the first solution with a first titanium compound to form the solid pre-catalyst component; and treating the solid pre-catalyst component with a hydrocarbon or halogenated hydrocarbon solvent, optionally containing a second titanium compound.
(FR) La présente invention concerne un procédé de préparation d'un composant de pré-catalyseur solide destiné à être utilisé dans la polymérisation oléfinique et qui consiste à dissoudre du chlorure de magnésium dans un alcool et éventuellement l'ajout d'eau pour former une première solution ayant une teneur en eau d'environ 0,5 mmol d'eau par mole de MgCl2 à environ 100 mmol d'eau par mole de MgCl2 ; mettre en contact la première solution avec un premier composé de titane pour former le composant de pré-catalyseur solide ; et traiter le composant de pré-catalyseur solide avec un hydrocarbure ou un solvant d'hydrocarbure halogéné, contenant facultativement un second composé de titane.
