Abstract

Se describe un proceso para agregar estabilizadores y, opcionalmente, aditivos, a poliolefinas en la forma de partículas obtenidas en un monómero líquido, por medio de catalizadores de Ziegler-Natta, en donde la adición de los estabilizadores y, opcionalmente, de los aditivos, se lleva a cabo en un monómero líquido en un paso que sigue a la polimerización, pero que procede a la vaporización instantánea del monómero líquido, después que el alquilo de aluminio ha sido desactivado.
