Abstract

Se describen métodos para controlar el hinchamiento del extruido de un polímero de olefina producido mediante el uso de un sistema de doble catalizador. El hinchamiento del extruido de polímero de olefina se puede aumentar o disminuir como una función de la relación en peso del catalizador y la relación molar del reactivo utilizadas durante el proceso de polimerización de olefina.
