Patent Number: 6,310,136

Title: Blends of biodegradable poly(hydroxy ester ether) thermoplastic with renewable proteins

Abstract: Compositions of the invention are produced by blending hydroxy-functional polyesters with proteins at elevated temperatures. These compositions can be shaped into articles by known processes such as extrusion, compression molding, and injection molding. 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.
