Abstract

L'invention concerne un film de polyester-amide étiré fabriqué à partir de copolymère de polyester-amide comprenant des unités de polyamide et des unités de polyester dans la chaîne moléculaire. Dans sa viscoélastométrie dynamique, le film étiré présente une crête de dispersion principale à une température supérieure d'au moins 10 °C à la température de la crête de dispersion principale d'un objet non orienté constitué d'un copolymère de polyester-amide. Ce film étiré est biodégradable et présente une excellente force mécanique et résistance thermique. Il peut être produit au moyen du procédé d'étirement et de gonflage.
