  Abstract

The viscoelastic behavior and tensile properties of PLA blends and PLA/PMMA/PBAT blends were measured, and an image analysis was performed, to examine the compatibility of PLA, PBAT, and PMMA. PLA/PMMA blends were found to exhibit a high level of compatibility for all compositions. The thermal stability, modulus, and tensile strength of these blends increased with PMMA content. Also, the glass transition temperature and tensile strength of PLA/PMMA blends varied between the values for neat PLA and PMMA, indicating a high degree of compatibility. On the other hand, ternary blends of PLA, PMMA, and PBAT exhibited a low modulus than PLA/PMMA blends; their compatibility improved with PMMA content because of PMMA acting as a compatibilizer for PLA/PBAT blends.
