Title
(ES) PROCESO PARA TRANSICIONAR ENTRE CATALIZADORES DE POLIMERIZACION INCOMPATIBLES
Abstract
(ES)
Esta invención se refiere a un proceso para transicionar entre sistemas catalizadores de polimerización que son incompatibles entre sí. Particularmente, la invención se refiere a un proceso para transicionar de una reacción de polimerización de olefinas que utiliza un sistema catalizador Ziegler-Natta tradicional a una reacción de polimerización de olefinas que utiliza un sistema catalizador de metaloceno.
