Polypropylene carbonate (PPC)/polylactic acid (PLA) blends of five different weight ratios were synthesized using a novel extruder (NE) that worked on the principal of generating global dynamic elongational flow, instead of using a traditional twin-screw extruder (TSE) that worked on the principal of generating shear flow. The miscibility and compatibility enhancement of PPC/PLA blends were investigated using mechanical testing, scanning electron microscopy (SEM), wide-angle X-ray diffraction (WAXD) and differential scanning calorimetry (DSC). The mechanical properties as functions of composition and strain to stress ratio illustrated good compatibility between PPC and PLA. The phase inversion of the PPC/PLA system occurred between 70 and 50 weight % of PLA in the PPC/PLA blends. On the other hand, SEM showed that the phase inversion of the PLA/PPC system took place between 70 and 50 weight percentages of PLA in the PLA/PPC blends. WAXD revealed two sharp reflection peaks at 70% PLA content. DSC indicated that partial miscibility and compatibility of PPC and PLA. In summary, the effect of the extensional force field preparation is better than shear force field.
