ABSTRACT:
Disclosed are blends of aliphatic-aromatic copolyesters with poly(ethylene-co-vinyl acetate) copolymers and shaped articles prepared therefrom. These blends have higher melt strength than the aliphatic-aromatic copolyester alone and exhibit increased melt strength and better processability. In addition, the blends and shaped articles show bio-disintegration and/or biodegradability in a composting environment.
