Effect of chain extender on morphology and tensile properties of poly(l-lactic acid)/poly(butylene succinate-co-l-lactate) blends

The effect of a multi-functional epoxy-based chain extender on the tensile properties of poly(l-lactic acid) (PLLA)/poly(butylene succinate-co-l-lactate) (PBSL) blends was investigated using X-ray diffraction, differential scanning calorimetry, attenuated total reflection infrared spectroscopy, solid-state nuclear magnetic resonance spectroscopy, and scanning electron microscopy. The PLLA/PBSL blend without the chain extender showed low strain...
