Abstract
Mezclas de polímeros, películas y sustratos recubiertos que incluyen las mezclas de polímeros. Las mezclas de polímeros incluyen al menos 90% en peso de polímero de polietileno de baja densidad y de 1 a 10% en peso de ionómero. El polímero de LDPE tiene un índice de fusión (I₂) de 2 g/10 min. a 6 g/10 min. y una distribución de peso molecular de 5 a 11 según lo determinado con un método de cromatografía de permeación en gel convencional. El ionómero incluye un copolímero de etileno y ácido, en el que de 15% a 70% de los grupos ácido están neutralizados con un catión de sodio en función de la cantidad total de grupos ácido en el copolímero de ácido. El copolímero de etileno y ácido es el producto de reacción polimerizado de: al menos 50% en peso de etileno, de 2% en peso a 40% en peso de monómero de ácido monocarboxílico, y de 0 a 20% en peso de acrilato de alquilo, en función del % en peso total de los monómeros presentes en el copolímero de etileno y ácido.
