Реферат: Un procedimiento para polimerización de olefinas que comprende poner en contacto: (a) etileno y al menos un comonómero seleccionado del grupo consistente en alfa-olefinas C4 a C8, y (b) un sistema catalizador soportado que comprende un compuesto catalizador de metaloceno, consistiendo el compuesto catalizador de metaloceno en un compuesto catalizador de bis-ciclopentadienil-zirconoceno que comprende al menos un grupo saliente fluoruro o que contiene flúor; en donde el proceso de polimerización es un proceso de fase gaseosa continuo, llevado a cabo a una temperatura mayor que 70ºC en un reactor capaz de producir polímero a una velocidad mayor que 227 kg/h. A process for polymerization of olefins comprising contacting: (a) ethylene and at least one comonomer selected from the group consisting of C4 to C8 alpha-olefins, and (b) a supported catalyst system comprising a metallocene catalyst compound, consisting the metallocene catalyst compound in a bis-cyclopentadienyl zirconocene catalyst compound comprising at least one fluoride leaving group or fluorine containing; wherein the polymerization process is a continuous gas phase process, carried out at a temperature greater than 70 ° C in a reactor capable of producing polymer at a speed greater than 227 kg / h.
