Abstract
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.
