Abstract

La présente invention concerne un système catalyseur métallocène comprenant une composition fonctionnellement stable, et un procédé de production de polyoléfine au moyen du système catalyseur métallocène. Plus particulièrement, en utilisant le système catalyseur métallocène comprenant : de 90 à 99,9 % en poids de composé métallocène d'un ou plusieurs types ; et de 0,1 à 10 % en poids d'une composition fonctionnellement stable comprenant un ou plusieurs types de composés choisis dans le groupe constitué par un sulfate, un sulfonate, un phosphate et un carboxylate, et un ou plusieurs types d'huile minérale blanche, l'activité unique du catalyseur est maintenue et les phénomènes d'encrassement et d'agglomération sont réduits au minimum pendant la polymérisation d'oléfines pour permettre au procédé d'être mis en œuvre de manière stable, et ainsi au moyen de la présente invention, un procédé de production de polyoléfine peut être fourni, et une polyoléfine produite peut être fournie.
