Abstract

The present invention relates to polymeric compositions that are biodegradable and that can be melt-processed into various forms, including films, fibers, and nonwovens. The compositions include compatible or semicompatible blends of biodegradable polymers and have physical and thermomechanical integrity. Films formed from preferred polymeric compositions are suitable for use as backsheets in disposable absorbent articles. In a preferred embodiment, the polymeric composition includes a polyhydroxyalkanoate and at least one other biodegradable polymer selected from aliphatic polyester-based polyurethanes, a polylactide, polycaprolactone, or a mixture of two or more of these polymers. Where the second polymer is polycaprolactone, the composition preferably also includes a third polymer for enhancing the melt processability of the composition.
