Poly(lactic acid) (PLA) is one of the most popular biodegradable polymers and has high tensile modulus and stiffness. However, PLA has a limit of the usage due to its low inherent toughness and impact resistance. On the other hand, poly(butylene adipate-co-terephthalate) (PBAT) is the another biodegradable polymer which has high ductility, but low compatiblity with PLA. Here, poly(butyl acrylate) (PBA) was added in PLA/PBAT to improve the compatibility and impact resistance. We analyzed the thermal, dynamic viscoelastic, morphological, mechanical and impact strength by DSC, DMA, SEM, UTM and Izod impact test. As the result, PLA/PBAT blends with PBA could be used as applications of eco-friendly plastics through enhancing the impact strength.
