Abstract

La presente invención trata de un proceso continuo y sistema de polimerización caracterizado por una incorporación separada de catalizador y aporte de un sobrante de agua, una composición de interpolímero de etileno caracterizada porque tiene una distribución de peso molecular amplia (MWD) y la optimización de la homogeneidad de su estructura, un procedimiento para la fabricación de tal composición y un artículo fabricado gracias a esa composición. La nueva composición se caracteriza porque tiene una relación del punto de fusión 10 2, de 8 a 10,4, una relación Mw/Mn mayor que 4 como se determina por cromatografía sobre gel, un índice de fusión I2 de 0,1 a 10 gramos/10 minutos, una densidad menor que 0,945 gramos/centímetro cúbico, y basado en el peso total de las partes de polímero cristalizables, un porcentaje ponderal en la temperatura del pico dominante superior a 75 0 C, tal como se determina por fraccionamiento de análisis cristalográfico en el intervalo de de 20 a 100 0 C, igual o mayor que el producto matemático de 1,7946x10 -28 x 10 31,839 x densidad de la composición, una densidad de la composición en gramos/centímetros cúbico. La nueva composición muestra una buena capacidad de proceso y propiedades mejoradas de tenacidad, especialmente una excelente resistencia del film a la rotura y a los impactos, y se aplica particularmente para uso en aplicaciones tales como el revestimiento de alta duración del interior de recipientes de basuras y la confección de bolsas muy resistentes.
