The present invention relates to a catalyst system containing at least one metallocene and at least one inertised support and preferably at least one co- catalyst. To produce the inertised support, at least one inorganic oxide is treated with at least one metal-organic compound, preferably in an inorganic solvent. The present invention also relates to a polymer with a melting point ? 158 ~C, a regio error proportion < 0.2 % and a triple activity > 98.0 %.
L'invention concerne un système de catalyseur qui contient au moins un métallocène et au moins un support rendu inerte, ainsi que de préférence au moins un co-catalyseur. Le support inertisé est obtenu par traitement d'au moins un oxyde inorganique avec au moins un composé organo-métallique, de préférence dans un solvant inorganique. Cette invention concerne en outre un polymère dont le point de fusion >/= 158 DEG C, l'activité triadique > 98,0 % et la part d'erreurs régiospécifiques < 0,2 %.
