PLLA/PBSC polymer blend was developed to improve the fracture property of PLLA. Fracture energy, J lmax, of PLLA/PBSC was evaluated, and compared with those of PLLA and PLLA/PCL blend. Dramatic improvement of J lmax was observed due to PBSC blending. Fracture surfaces were also observed using SEM, and ductile deformation of micro-fibrils was seen on the surfaces of the blends, compared to the brittle surface of PLLA. Miscibility of PLLA and PBSC appears to be much better than that of PLLA and PCL in which PCL spherulites are distributed in the continuous phase. Thus, the miscibility plays an important role in the improvement of fracture property of these biodegradable polymer blends.
