Zusammenfassung: | The present invention relates to a new solid catalytic component, which can be used in combination with an aluminum compound as co-catalyst and optionally an external electron donor as additional co-catalyst to form a catalytic system of the Ziegler-Natta-catalyst-type. The solid catalytic system comprises titanium or vanadium compound, a compound of magnesium containing at least one halogen, a particulate porous support, and optionally an internal electron donor.
La presente invencion se refiere a un nuevo componente catalitico solido que puede ser usado en combinacion con un compuesto de aluminio como co-catalizador, y opcionalmente, con un donador externo de electrones como co-catalizador adicional, para formar un sistema catalitico del tipo de Ziegler-Natta. El sistema catalitico solido comprende un compuesto de titanio o de vanadio, un compuesto de magnesio que contiene por lo menos un halogeno, un soporte poroso en particulas y, opcionalmente, un donador interno de electrones. |
