Title: (DE) OLEFINPOLYMERISATIONSKATALYSATOR AUS EINER TRIALKYLALUMINIUMMISCHUNG, KIESELSÄUREGEL UND METALLOCEN.

(FR) CATALYSEUR DE POLYMERISATION D'OLEFINES OBTENU A PARTIR D'UN MELANGE DE TRIALYLE ALUMINIUM, DE GEL DE SILICE ET D'UN METALLOCENE.
Abstract:
(EN) A high activity alumoxane-metallocene supported catalyst for the polymerization of 1-olefins prepared by reacting undehydrated silica gel with a mixture of trimethylaluminum and triisobutylaluminum to produce a silica-alumoxane product which is then reacted with a Group IVB and/or Group VB metallocene to produce an active catalyst which may be obtained in powder form, suitable for use in gas or slurry phase reactors, by a removal of solvents and drying.
(FR) Un catalyseur très actif, à support d'alumoxane-métallocène, pour la polymérisation de 1-oléfines est préparé en faisant réagir un gel de silice non déshydraté avec un mélange de triméthyle aluminium et de triisobutylealuminium pour obtenir un produit de silice-alumoxane que l'on fait réagir ensuite avec un métallocène du groupe IVB et/ou du groupe VB de manière à obtenir un catalyseur actif sous forme de poudre appropriée à une utilisation dans des réacteurs de phase gazeuse ou boueuse, par élimination de solvants et par séchage.
