Abstract

En un proceso que comprende hacer tomar contacto al etileno por sí solo o al etileno y a uno o más comonomeros en uno o más reactores de lecho fluidificadobajo condiciones de polimerizacion, con un sistema catalizador caracterizado por comprender:(i )un proceso de magnesio/titanio con o sin soporte en forma delechada, caracterizado por contener un donante de electrones; y (ii)un activador en una cantidad suficiente para completar la activacion del precursor. Eladelanto está caracterizadopor: 1) mezclar el precursor y el activador previo a su introduccion dentro del reactor en dos o tres etapas, la ultima de lascuales es una etapa de coronacion en la cual se completa la activacion; 2)mantener la mezcla del paso (A) en forma delechada, y 3)i ntroducir la mezcla de paso(B) dentro del reactor con las siguientes condiciones (I)la relacion atomica del aluminio respecto del titanio se encuentra en el rango de aproximadamente 1:1a aproximadamente 15:1 y la relacion molar delactivador respecto del donante de electrones es de aproximadamente 1:1 a aproximadamente 2:1.(II)el activador esun compuesto o una mezcla secuencial de dos compuestos diferentes; (III)cada compuesto activador posee la formula Al(Rn)X(3-n), en lacual cara R es,indepen dientemente, un radical hidrocarburo alifático saturado que posee C1-14, cada X es independientemente cloro, bromo, o yodo y n es 1 a 3; (IV)laactivacion del precursor se encuentra esencialmente completa previo a laintroduccion del precursor dentro del reactor; y (V)no se introduce ningun activadoradicional dentro del (de los) reactor(es).
