Title (EN) CATALYST SOLID COMPRISING PYROGENIC SILICA FOR OLEFIN POLYMERIZATION
(FR) SOLIDE CATALYTIQUE COMPRENANT DE LA SILICE PYROGENE POUR POLYMERISATION D'OLEFINES
Abstract: front page image
(EN)A catalyst solid comprising: A) support particles having a mean particle diameter d¿50? of from 5 to 200 $g(m)m and a specific surface area of from 30 to 1 000 m?2¿/g and obtainable by agglomeration of primary particles of a pyrogenic silica having a mean particle diameter d¿50? of from 1 to 50 nm, and B) at least one organic transition metal compound, can be used for the polymerization or copolymerization of olefins.
(FR)L'invention concerne un solide catalytique comprenant A) des particules support ayant un diamètre particulaire moyen d50 compris entre 5 et 200 $g(m)m et une aire spécifique comprise entre 30 et 1000 m2/g pouvant être obtenues par agglomération de particules primaires d'une silice pyrogène ayant un diamètre particulaire moyen d50 compris entre 1 et 50 nm, et B) au moins un composé métallique de transition organique, que l'on peut utiliser pour la polymérisation ou la copolymérisation d'oléfines.
