Abstract

Se describen mezclas poliméricas adecuadas para envasado que incluyen un metal de transicion; uno o más homopolímeros o copolímeros de poliamida; y uno o más homopolímeros o copolímeros de tereftalato de polietileno obtenidos mediante una polimerizacion de fase fundida utilizando un sistema catalizador que comprende átomos de aluminio en una cantidad, por ejemplo, entre aproximadamente 3 ppm y aproximadamente 60 ppm y uno o más átomos de metales alcalinotérreos, átomos de metales alcalinos, o residuos de compuestos alcalinos en una cantidad, por ejemplo, entre aproximadamente 1 ppm y aproximadamente 25 ppm, en cada caso en base al peso del uno o más homopolímeros o copolímeros de tereftalato de polietileno. Las mezclas poliméricas descritas exhiben actividad depuradora de oxígeno mejorada en comparacion con las mezclas preparadas utilizando polímeros preparados con sistemas catalizadores convencionales.
