Biodegradable polymer blend compositions are provided which contain
oligomeric esters. The oligoester compound can compatibilize blends of two
or more biodegradable polymers resulting in excellent ductility and
reduced tendency to embrittlement of products produced from therefrom. In
a preferred embodiment of the invention, the blend composition comprises a
PHA, polycaprolactone (PCL) and one or more oligomeric esters. In another
preferred embodiment of the invention, the blend composition comprises a
PHA, polybutylenesuccinate-adipate (PBSUA), and one or more oligomeric
esters.
