ABSTRACT:
Compositions of the invention include particular hydroxy-functional polyesters and a natural polymer. Among articles that can be made from such compositions are those with sufficiently strong tensile strengths as to form disposable utensils. However, the compositions are more environmentally friendly than commodity plastics such as polyethylene or polystyrene. Starches are particularly preferred as the natural polymers for inclusion in the compositions.
