Beschreibung
Zusammenfassung:	The present invention relates to biodegradable multiphase compositions comprising a continuous phase composed of a matrix of at least one tough hydrophobic polymer incompatible with the starch and a nanoparticulate dispersed starch phase with mean dimensions of less than 0.25 m. The compositions are characterized by breaking load, Young's Modulus and breaking energy. L'invention concerne des compositions biodégradables multiphases comprenant une phase continue composée d'au moins une matrice d'au moins un polymère hydrophobe résistant incompatible avec l'amidon et une phase d'amidon nanoparticulaire dispersée à dimensions moyennes inférieures à 0,25 m. Ces compositions sont caractérisées par une charge de rupture, un module de Young et une énergie de rupture.
