Title (EN) PREPOLYMERIZED CATALYST COMPONENTS FOR THE POLYMERIZATION OF OLEFINS
(FR) COMPOSANTS DE CATALYSEUR PRÉPOLYMÉRISÉ POUR LA POLYMÉRISATION D’OLÉFINES
Abstract:
(EN) A Prepolymerized catalyst component for the polymerization of olefins comprising a solid catalyst component which comprises Mg, Ti, and chlorine atoms and an electron donor (ID) said prepolymerized catalyst component being characterized by the fact that: - the electron donor (ID) is constituted by at least 80%mol of 1,3 diethers with respect to the total molar amount of electron donor compounds; -the prepolymerized catalyst has a porosity due to pores with diameters up to Ιμιη of less than 0.2 cm3/g; -it contains an amount of ethylene prepolymer of less than 45% with respect to the total weight of prepolymerized catalyst.
(FR) Cette invention concerne un composant de catalyseur prépolymérisé pour la polymérisation d'oléfines comprenant un composant catalytique solide qui comprend du Mg, du Ti, et des atomes de chlore et un donneur d'électrons (ID), ledit composant catalyseur prépolymérisé étant caractérisé en ce que : - le donneur d'électrons (ID) est constitué par au moins 80 % en mol de 1,3-diéthers par rapport à la quantité molaire totale des composés donneurs d'électrons ; - le catalyseur prépolymérisé a une porosité due à des pores ayant des diamètres jusqu'à 1 µm inférieure à 0,2 cm3/g ; - il contient une quantité de prépolymère d'éthylène inférieure à 45 % par rapport au poids total de catalyseur prépolymérisé.
