Biodegradable PLLA was toughened by blending with four different ductile bio-polymers such as PBS, PCL, PBSL and PBSC using a technique of melt-mixing. Mechanical properties were measured and compared to assess their effectiveness as a blending partner for PLLA. It was found that the bending properties are the best with PBS; on the other hand, the mode I fracture toughness and impact resistance are most improved with PBSC. For PLLA/PBSC, FE-SEM observation showed that the fracture surface exhibited ductile fracture with elongated fibrils, and POM result clearly indicated that the largest damage zone is generated in the vicinity of crack-tip, suggesting the highest energy dissipation in the crack-tip region.
