Title (EN) PROCESS FOR PRODUCING POLYPROPYLENE
(FR) PROCEDE DE PRODUCTION DE POLYPROPYLENE
Abstract:
(EN) The invention concerns a process for producing propylene, and polypropylenes produced thereby. According to the process, propylene is homo- or copolymerized in a reaction sequence including at least one bulk reaction zone and at least one gas phase reaction zone arranged in series. The polymerization is carried out in the presence of a Ziegler-Natta type catalyst system including a catalyst component, a cocatalyst component and an external donor. According to the invention the catalyst component, the external donor and a part of the cocatalyst component are fed to a first reaction zone, and the rest of said cocatalyst component is fed to a second reaction zone.
(FR) L'invention concerne un procédé de production de propylène, et des polypropylènes ainsi produits. Selon ce procédé, le propylène est homo- ou copolymérisé dans une séquence de réactions comprenant une zone de réaction en vrac et au moins une zone de réaction par phase gazeuse disposées en série. La polymérisation est réalisée en présence d'un système catalyseur de type Ziegler-Natta contenant un composé catalyseur, un composé cocatalyseur et un donneur externe. Selon cette invention, le composé catalyseur, le donneur externe et une partie du composé cocatalyseur sont amenés vers une première zone de réaction, et le reste dudit composé cocatalyseur est amené vers une seconde zone de réaction.
