Abstract

Una composicion de poliolefina resistente a la fragilidad que incluye: (a) por lo menos 80 por ciento en peso, basado en el peso total de la composicion de poliolefina, de un polímero cristalino que comprende ya sea un homopolímero de propileno que tiene un índice isotáctico mayor que 90 o un copolímero al azar de propileno y ya sea etileno o 1-olefinas de 4 a 10 átomos de carbono, (b) un copolímero elastomérico de etileno ya sea propileno o buten-1, en donde el copolímero elastomérico está presente en una cantidad suficiente para mejorar la flexibilidad de la composicion de poliolefina, sin afectar perjudicialmente la claridad de la composicion de poliolefina, y en donde la composicion de poliolefina tiene una temperatura de distorsion térmica de por lo menos 60 degree C. Los componentes opcionales incluyen una cantidad estabilizadora de un estabilizador de luz de amina impedida, un agente de neutralizacion de ácido y un compuesto a base de sorbitol. La composicion se puede usar para fabricar artículos médicos y material para empaquetado de alimentos que deben esterilizarse, ya sea mediante irradiacion o mediante tratamiento en autoclave.
