Abstract

Composición de polímeros de etileno de extrusión que tienen elevado escurrimiento y neck-in-rechupe o estiramiento reducido, un proceso parautilizar dicha composición para preparar recubrimientos por extrusión, perfiles y películas moldeadasy artículos que incluyan dicha composición. Lacomposición de polímero de extrusión se obtiene de 75-95% en peso de al menos un interpolímero de etileno y 5-25% en peso de al menos un polímero de etilenode alta presión, el cual tiene un índice de fusión menor de 6,0 g/10 minutos, una densidad de al menos 0,916 g/ml, una resistencia en fusión de al menos 9cN, según se determina con las unidades Rheotens Gottfert a 190°C, a relaciones Mw/Mn de al menos 7,0 y con distribución bimodal del peso molecular. Lacomposición de extrusión tiene un índice de fusión, I2, de al menos 1,0 g/10 minutos y los artículos que incluyen la composición pueden ser utilizados comosellantes, adhesivos o en capas de desgaste.
