Abstract

La invención se refiere a un proceso para la preparación de polímeros de olefina mediante la polimerización que utiliza un catalizador de metal detransición, con la adición de un fosfito de aminoalquil-1,1-bifenil-2,2-diilo o fosfito de aminoalquil-2,2-alquiliden-bis(fenilo), en conjunto conmodificadores adicionales opcionales. Los polímeros que se pueden obtener de esta manera, tienen una excelente estabilidad a largo plazo.
