Thermoplastic polymer compositions comprising starch and articles made therefrom are water stable or may be rendered so. One method of making water stable thermoplastic compositions comprises the steps of mixing destructured starch with polyhydric alcohol and triglyceride, and forming a transesterification reaction product from at least a portion of the polyhydric alcohol and triglyceride.

L'invention concerne des compositions polymères thermoplastiques comprenant de l'amidon et des articles à base de ces compositions qui sont ou qui peuvent être rendus stables à l'eau. Un procédé de fabrication de compositions thermoplastiques stables à l'eau consiste à mélanger de l'amidon destructuré avec de l'alcool polyhydrique et du triglycéride, et à former un produit de réaction de transestérification à partir d'au moins une partie de l'alcool polyhydrique et du triglycéride.
