Homogeneous blends of PDLLA/PCL prepared using a solvent-evaporation technique Adding PCL to PDLLA changes its fracture behavior from brittle toward soft The PCL improves elongation and creep recovery, but decreases strength and stiffness The creep behavior can be nicely modeled with power law and Weibull distribution
