Abstract

Una composición de poliolefina adecuada para preparar membranas para techos de capa simple, que comprende: (A) entre aproximadamente 15% y aproximadamente 40% en peso de un copolímero cristalino de propileno con al menos una a-olefina de fórmula H2C=CHR1, donde R1 es H o un alquilo C2-8 recto o ramificado, con contenido de al menos aproximadamente 90% en peso de propileno, con una solubilidad en xileno a temperatura ambiente menor a aproximadamente 15% en peso; (B) entre aproximadamente 60% y aproximadamente 85% en peso de una fracción elastomérica que comprende: (1) un copolímero de propileno con etileno con contenido de aproximadamente 20% a aproximadamente 35% en peso de etileno, y con una solubilidad en xileno a temperatura ambiente superior a aproximadamente 70% en peso, donde la viscosidad intrínseca de la fracción soluble en xileno es superior a aproximadamente entre 3,0 dl/g y aproximadamente 6,0 dl/g; y (2) un copolímero de etileno con al menos una alfa-olefina de fórmula H2C=CHR2, donde R2 es un alquilo C2-8 recto o ramificado con contenido de aproximadamente 15% en peso a 40% en peso de a-olefina, y que tiene una solubilidad en xileno a temperatura ambiente superior a aproximadamente 25% en peso, donde la viscosidad intrínseca de la fracción soluble en xileno varía entre aproximadamente 0,5 dl/g y aproximadamente 5,0 dl/g; donde la relación en peso entre (1) y (2) varía entre aproximadamente 1:5 y aproximadamente 5:1. La composición de poliolefina, preferentemente preparada por polimerizacfión secuencial en al menos tres etapas, tiene una resistencia a la tracción a la rotura l 25 MPa, una elongación a la rotura l 700 MPa y una tesura l 150 MPa.
