The aim of this study has been to gain a fundamental understanding of the mechanisms and conditions governing thermal degradation of poly (lactic acid) (PLA), poly (butylene-adipate-co-terephtalate) (PBAT) and their blends upon processing conditions. Thermal degradation of biodegradable PLA and PBAT...
