Title (EN) OLEFIN POLYMERISATION CATALYST AND METHODS FOR PREPARING THE SAME
(FR) CATALYSEUR DE POLYMERISATION D'OLEFINES ET PROCEDES DE FABRICATION CORRESPONDANTS
Abstract:
(EN) The present invention relates to an olefin polymerisation catalyst comprising a catalyst component in the form of particles having a predetermined size range and a low surface area, but high activity, said catalyst being suitable for use in olefin polymerisation, to the process for preparing the catalysts as such and to their use in polymerisation olefins. Is claimed a Ziegler-Natta catalyst for olefin polymerisation in the form of solidified particles according to claim 1 wherein said distribution of active sites is being effected during the solidification step to form said particles.
(FR) L'invention concerne un catalyseur de polymérisation d'oléfines qui comprend un composant catalytique comportant des particules à étendue granulométrique prédéterminée et avec une aire superficielle réduite mais présentant une activité élevée. Ce catalyseur peut être utilisé en polymérisation d'oléfines. L'invention concerne aussi un procédé de fabrication de tels catalyseurs et leur utilisation dans les oléfines obtenues par polymérisation. L'invention concerne un catalyseur de polymérisation Ziegler-Natta, qui comporte des particules solidifiées, conformément à la revendication 1, la distribution des sites actifs étant réalisée pendant la solidification pour former lesdites particules.
