Heterophasic compositions comprising starch and a thermoplastic polymer that is incompatible with the starch, in which the starch constitutes the discontinuous phase and the thermoplastic polymer the continuous matrix, having an impact strength greater than 30 KJ/m2 (measured on blown film of 30 microns thick at 10°C and RH less than 5 %), and further characterised by the presence in the X-ray diffraction spectrum of a peak at an angle 2-theta from 13 to 14° the ratio of the intensity of which to that of the peak of the amorphous starch which occurs at 20.5°, is less than 2 and greater than 0.02.

L'invention porte sur des compositions hétérophasiques comprenant de l'amidon et un polymère thermoplastique incompatible avec l'amidon. L'amidon constitue la phase discontinue et le polymère thermoplastique la matrice continue et présente une résistance au choc supérieure à 30 KJ/m<2> (mesurée sur un film soufflé de 30 microns d'épaisseur, à 10 DEG C, et présentant une humidité relative inférieure à 5 %). L'invention se caractérise également en ce que le spectre de diffraction de rayons X des compositions présente une crête au niveau d'un angle thêta 2 compris entre 13 et 14 DEG dont le rapport d'intensité en relation avec celui de la crête de l'amidon amorphe apparaissant au niveau d'un angle de 20,5 DEG est inférieur à 2 et supérieur à 0,2.
