Abstract

Una composicion de copolímero resistente a la fragilidad que incluye: (a) una composicion de polímero reducida a una viscosidad que comprende un copolímero cristalino al azar de propileno y ya sea etileno o 1-olefinas de 4 a 10 átomos de carbono, y (b) una cantidad de 3-oxi-[4-(2,2,6,6-tetrametil)piperidinil] siloxano de polimetilpropilo, que es efectivo para mejorar la resistencia a la radiacion de la composicion. Los componentes opcionales incluyen un agente de neutralizacion de ácido, y un compuesto clarificador a base de sorbitol. La composicion se puede usar para fabricar artículos médicos y material para empaquetadura de alimentos que deben esterilizarse, ya sea mediante irradiacion o mediante tratamiento en autoclave.
