Patent

CA 2262396

The invention relates to a catalyst system obtained by mixing at least one metallocene, at least one co-catalyst and at least one support which is rendered inert. The invention further relates to a method for producing a free flowing supported catalyst system wherein a) a metallocene/co-catalyst mixture is produced in a solvent or suspension agent, b) the metallocene/co-catalyst mixture is applied to a porous preferably inorganic dehydrated support, c) the solvent is removed from the resulting mixture, d) the supported catalyst system is isolated. The present invention also relates to homopolymers and/or co-polymers having the preferred formula Rm-CH=CH-Rn for the monomer, wherein Rm and Rn are the same or different and mean a hydrogen atom or a group containing carbon with 1 to 10 C atoms, and Rm and Rn can form one or several rings with the binding atoms, which can be obtained with a catalyst system. Finally, the invention relates to the use of the inventive polymers fro producing tear-resistant, hard and stiff shaped bodies such as fibers, filaments, injection-molded parts, films, plates or large hollow bodies such as tubes.

L'invention concerne un système de catalyseur obtenu par mélange d'un cocatalyseur et d'au moins un support rendu inerte. L'invention concerne en outre un procédé de production d'un système de catalyseur porté à écoulement libre, selon lequel: a) un mélange métallocène/cocatalyseur est produit dans un solvant ou un agent de suspension, b) le mélange métallocène/catalyseur est appliqué sur un support poreux, de préférence un support déshydraté inorganique, c) le solvant est extrait du mélange obtenu, d) le système de catalyseur sur support est isolé. L'invention concerne en outre des homo- et/ou des copolymères ayant la formule préférée R¿m?-CH=CH-R¿n? pour le monomère, où R¿m? et R¿n? sont identiques ou différents et désignent un atome d'hydrogène ou un groupe contenant du carbone ayant entre 1 et 10 atomes de C et R¿m? et R¿n? peuvent former conjointement avec les atomes qui les lient un ou plusieurs composés cycliques, s'obtenant avec un système de catalyseur. L'invention concerne enfin l'utilisation des polymères obtenus selon l'invention pour produire des corps moulés durs et rigides résistant à la déchirure, tels que des fibres, des filaments, des pièces moulées par injection, des films, des plaques ou des corps creux importants, tels que des tuyaux.
