Abstract

Se proporciona un método de transición de catalizadores para la polimerización de poliolefina. En una aspecto, el proceso comprende proporcionar un reactor de polimerización que comprende un primer sistema catalizador, poner en contacto monómero de olefina con el primer sistema catalizador a fin de formar poliolefina en una primera reacción de polimerización e introducir un anticatalizador en el reactor de polimerización, en una cantidad suficiente para finalizar la primera reacción de polimerización. El método además comprende introducir un segundo sistema catalizador en el reactor de polimerización, en presencia de por lo menos una porción del anticatalizador, en donde al menos la única porción del anticatalizador es una cantidad suficiente para activar el segundo sistema catalizador; y poner en contacto monómeros de olefina con el segundo sistema catalizador, a fin de formar poliolefina en una segunda reacción de polimerización.
