Title (EN) PROCESS FOR THE POLYMERIZATION OF OLEFINS
(FR) PROCÉDÉ DE POLYMÉRISATION D'OLÉFINES
Abstract:
(EN) A gas-phase process for the homo or copolymerization of olefins carried out in the presence of a catalyst system formed by a contacting in a liquid hydrocarbon and in the presence of hydrogen (a) a solid catalyst component comprising a Ti, Mg and C1, and optionally an internal electron donor compound, (b) an aluminum alkyl compound and optionally (c) an external donor compound.
(FR) Un procédé en phase gazeuse pour l'homopolymérisation ou la copolymérisation d'oléfines mises en oeuvre en présence d'un système catalyseur formé par une mise en contact, dans un hydrocarbure liquide et en présence d'hydrogène, (a) d'un composant catalyseur solide comprenant un Ti, Mg et c1, et éventullement un composé donneur d'électrons interne, (b) d'un composé alkyle d'aluminium et éventuellement (c) d'un composé donneur externe.
