Abstract
Provided are modified bio-derived polymers having improved processability as well as methods of producing such polymers and articles produced therefrom. The modified bio-derived polymers have improved melt strength compared with presently available bio-derived polymers. Thus, the inventive bio-derived polymers are suitable for use in plastic processing techniques such as blow molding and blown film extrusion.
