Abstract
Un método para mejorar el color y la resistencia al impacto de un polímero de nitrilo producido por la polimerización de un nitrilo olefínicamente insaturado y un componente de caucho preformado, teniendo dicho polímero al menos 50% en peso del nitrilo, por calentamiento del polímero a un estado plástico en ausencia de oxígeno y en presencia de un gas inerte.
