Abstract
Mejoras introducidas en un procedimiento para la modificación de polímeros, caracterizadas por calentar un polímero preparado por polimerización de al menos una 1-olefina alifática que no tiene más de 4 átomos de carbono por molécula en presencia de un catalizador que comprende óxido de cromo como ingrediente esencial, realizándose dicho calentamiento a una temperatura en la gama de 315 a 482º C durante un período menor de 30 minutos, y recuperar un polímero modificado.
