Abstract	1 General Introduction Poly (lactic acid) (PLA), a linear aliphatic polymer, is known as a biodegradable thermoplastic polymer with widely potential applications [1, 2]. PLA has a number of interesting properties including biodegradability, biocompatibility, high strength, and high modulus [3]. For this reasons, PLA is a candidate for producing package materials. However, its high brittleness and low toughness limit its application [4]. To overcome these limitations, blending PLA with flexible polymers is a practical and economical way to obtain toughened PLA. Poly (butylene adipate-co-terepthalate) (PBAT), an aliphatic-aromatic copolyester, is considered a good candidate for the toughening of PLA due to its high toughness and biodegradability [5]. Binary blends of PLA and PBAT exhibited higher elongation at break but lower tensile strength and modulus than the pure PLA due to the addition of a ductile phase. Therefore, the addition of filler to PLA/PBAT blends led to a modulus approaching that of the pure PLA. Unfortunately, PLA blends and PLA filled with natural materials e.g. natural fiber, calcium carbonate (CaCO3) have poor mechanical properties due to the poor interfacial adhesion. Maleic anhydride grafted PLA (PLA-gMA) has been used to improve the interfacial adhesion between PLA and other polymers [6, 7, 8] or PLA and fillers [9, 10, 11]. CaCO3 is selected in this study since it yields a cost reduction in polymer and can influence mechanical properties. The objective of this work was to investigate the effects of PLA-g-MA and CaCO3 on mechanical, morphological, and thermal properties of PLA/PBAT blend. 2 Experimental
