Abstract
Un sistema catalítico con una actividad aumentada para la (co) polimerizacion de alfa-olefinas, comprende un catalizador del tipo metaloceno, el cual es capaz de polimerizar olefinas sin aluminoxano y un compuesto polar de coordinacion débil. El proceso de polimerizacion basado en este sistema catalítico, permite que se obtenga mayor productividad con respecto a un proceso análogo llevado a cabo con el catalizador del tipo metaloceno como tal.
