논문초록 PLA/PBAT blends are highly promising materials in the field of biodegradable polymers. The possiblility of optimizing PLA/PBAT properties requires an improvement of compatability. The transesterfication during the melt blending of PLA and PBAT was investigated in presence of titanium butoxide as a catalyst. Tensile tests were performed to observe mechanical properties with compression moulded blends. Thermal properties of blends were studied by analyzing the differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). These results showed that compatibility of PLA and PBAT was improved through transesterfication and that the best content of catalyst was observed at 0.1 phr.
