Development and characterization of high-toughness biodegradable PLA/PBSA blends
The inherent brittleness of poly(lactic acid) (PLA) limits its use. This study demonstrates that blending with poly(butylene succinate-co-adipate) (PBSA) in combination with a chain extender (J-4468) overcomes this limitation. A transition in mechanical behavior is observed, with optimal toughness achieved in PBSA-rich...
