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 acid, and forming an ester condensation reaction product from at least a portion of the polyhydric alcohol and acid. In some embodiments, a pre-polymer formed from the ester condensation reaction may be provided as a pre-polymer that is mixed with the starch.
