Abstract

La presente se refiere a un método de preparación de un polipropileno de reología controlada caracterizado porque comprende una etapa de mezclado de un polímero de propileno con al menos un peróxido orgánico de baja reactividad. El polipropileno de reología de la presente puede ser aplicado a la producción de fibras, en procedimientos de soplado por fusión (melt blown"), en adhesivos de fusión en caliente (hot melt), en tejidos no tejidos de filamentos fusionados (spunbond) y en artículos moldeados por inyección.
