Abstract
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.
