Beschreibung
Zusammenfassung:	Supported catalyst compositions, useful in olefin polymerization, and having improved flow properties are disclosed. The catalyst compositions may be characterized by low macro pore volume and high bulk density. Methods for preparing the catalyst compositions are also disclosed. L'invention concerne des compositions de catalyseur supporté, utiles dans la polymérisation d'oléfines et aux propriétés de coulabilité améliorées. Les compositions de catalyseur peuvent être caractérisées par un faible volume de pores et une densité apparente élevée. L'invention concerne également des procédés de préparation des compositions de catalyseur.
