Title (EN) PROCESS FOR THE PREPARATION OF HIGH PURITY PROPYLENE POLYMERS
(FR) PROCÉDÉ DE PRÉPARATION DE POLYMÈRES DE PROPYLÈNE DE PURETÉ ÉLEVÉE
Abstract: front page image
(EN)A process for the preparation of high purity propylene polymers carried out in the presence of a catalyst comprising the product obtained by reacting:- an organo-aluminium compound, with - a solid catalyst component comprising Mg, Ti and electron donor compound selected from specific diolesters, said process being carried out employing an organo-aluminum/propylene ratio equal to or lower than 1.75 mmole/kg.
(FR)Cette invention concerne un procédé de préparation de polymères de propylène de pureté élevée mis en œuvre en présence d'un catalyseur comprenant le produit obtenu par réaction : - d'un composé organoaluminium avec - un composant de catalyseur solide comprenant du Mg, du Ti, et un composé donneur d'électrons choisi parmi des diol esters spécifiques, ledit procédé étant mis en œuvre dans un rapport d'organoaluminium/propylène égal ou inférieur à 1,75 mmoles/kg.
