Abstract
La presente consiste en una composicion mejorada de polímero etilénico de baja densidad y un método para prepararla. La composicion polimérica de acuerdo con la presente incluye un componente principal, y un componente secundario. El componente principal es una resina de LDPE que posee un índice de fusion (I2) en el orden de aproximadamente 0,01 dg/min hasta aproximadamente 100 dg/min, una relacion Mp(abs)/Mp(GPC) de aproximadamente 2,6 o menos, y una resistencia a la fusion inferior a (14,0 e(-1,05+log10(IF)))cN. El componente secundario es una resina de LDPE que posee un índice de fusion (I2) inferior a aproximadamente 5 dg/min, una distribucion de peso molecular superior a aproximadamente 7, y una relacion Mp(abs)/Mp(GPC) de por lo menos 2,7. La composicion polimérica de la presente puede incluir, además, componentes adicionales. Asimismo, el proceso de polimerizacion de iniciacion de radicales libres de acuerdo con la presente incluye los siguientes pasos: proporcionar etileno; y hacer reaccionar el etileno en un sistema de reactores, que incluye por lo menos un reactor tubular y por lo menos un reactor autoclave, a un rango de presion elevada de aproximadamente 18.000 psig hasta aproximadamente 55.000 psig, a una temperatura de reactor de aproximadamente 190 degree C hasta aproximadamente 400 degree C, en donde la carga de etileno en los reactores se divide en multiples corrientes de carga de etileno, y por lo menos una de las corrientes de carga del etileno en el reactor tubular comprende esencialmente etileno no reaccionado. Adicionalmente. El proceso de polimerizacion de iniciacion de radicales libres de acuerdo con la presente puede incluir además los pasos de proporcionar por lo menos uno o más comonomeros; y hacer reaccionar el etileno y el/los comonomero/s en el sistema de reactores a un rango de levada presion de aproximadamente 18.000 psig hasta aproximadamente 55.000 psig, a una temperatura de reactor de aproximadamente 190 degree C hasta aproximadamente 400 degree C.
