Abstract

Se revela un método de producir poliolefina con un índice de flujo de fusion objetivo y relacion de flujo de fusion. El método polimeriza uno o más monomeros olefínicos en un reactor simple que contiene un sistema de catalizador bicomponente. El sistema de catalizador incluye un primer componente catalizador y un segundo componente catalizador, cada uno de ellos caracterizado por una productividad catalizadora y una respuesta del agente de transferencia de cadenas. El reactor unico tiene una concentracion de agente de transferencia de cadena y una temperatura. La productividad del segundo componente catalizador tiene una dependencia de temperatura substancialmente diferente de aquella del primer componente catalizador. La temperatura del reactor es ajustada de modo tal que el alcance del flujo de fusion se acerque al valor que se desea llegar. La concentracion del agente de transferencia de cadenas en el reactor se ajusta de modo tal que el índice de fusion se acerque al valor blanco o valor al que se desea llegar sin cambiar substancialmente el alcance del flujo de fusion.
