Improved catalyst compositions, and polymerization processes using such improved catalyst compositions, are provided. An example of an improved catalyst composition is a supported catalyst system that includes at least one titanium compound, at least one magnesium compound, at least one electron donor compound, at least one activator compound, and at least one silica support material, the at least one silica support material having a median particle size in the range of from 20 to 50 microns with no more than 10% of the particles having a size less than 10 microns and no more than 10% of the particles having a size greater than 50 microns and average pore diameter of at least >= 220 angstroms.
L'invention concerne des compositions catalytiques améliorées, et des procédés de polymérisation utilisant de telles compositions catalytiques améliorées. Un exemple de composition catalytique améliorée est fourni par un système catalytique supporté incluant au moins un composé du titane, au moins un composé du magnésium, au moins un composé donneur d'électron, au moins un composé activateur, et au moins un matériau support à base de silice, le ou les matériaux supports à base de silice ayant une taille de particules médiane comprise dans la gamme allant de 20 à 50 microns, au plus 10 % des particules ayant une taille inférieure à 10 microns, et au plus 10 % des particules ayant une taille supérieure à 50 microns, et un diamètre de pores moyen au moins >= 220 angströms.
