Abstract

Esta invencion provee un método para introducir catalizadores multiples en un reactor en fase de gas o de suspension. Preferiblemente el método incluye lasetapas de introducir una o más olefinas y un primer catalizador y un activador en el reactor ydejar polimerizar las olefinas obteniendo una poliolefina eintroducir un segundo catalizador y un activador opcional en la primera catalizador/activador y a continuacion introducir la combinacion en el reactor y dejarpolimerizar las olefinas. Estain vencion provee además un método para introducir catalizadores multiples en un reactor de fase de gas o suspension que incluyenintroducir una o más olefinas, un primer catalizador y un activador y un segundo catalizador y un activador opcional enel r eactor, donde todos loscatalizadores y activadores se combinan conjuntamente antes de introducirlos en el reactor.
