Abstract

Un proceso continuo de polimerización en solución en el que se emplean por lo menos dos formulaciones de catalizadores. Se emplea una primera formulación de catalizador homogéneo en un primer reactor para producir un primer interpolímero de etileno y se emplea una primera formulación de catalizador heterogéneo en un segundo reactor para producir un segundo interpolímero de etileno. Opcionalmente, en un tercer reactor se forma un tercer interpolímero de etileno. Los productos de interpolímeros de etileno que se obtienen como resultado poseen propiedades deseables en una variedad de aplicaciones de uso final, por ejemplo en aplicaciones en películas. Se divulga un medio para incrementar el peso molecular del primer interpolímero de etileno y/o un medio para incrementar la temperatura del primer reactor, con relación a una tercera formulación de catalizador homogéneo. Se divulga un medio para reducir la proporción en peso de (a-olefina / etileno) en el primer reactor y/o reducir la densidad del primer interpolímero de etileno, con relación a una tercera formulación de catalizador homogéneo.
