Abstract Polyethylene glycol (PEG) was added at different concentrations to the blend of poly(L-lactic acid) (PLLA) and
poly(D,L-lactic acid)(PDLLA) to tailor the properties. The differential scanning calorimetry (DSC) measurement
showed that all blends were miscible due to shifting a single glass transition temperature into a lower temperature
for increasing PEG content. The DSC, FTIR, and XRD results implied the crystallinity enhancement for PEG content until 8 wt%, then decreased at 12 wt% PEG. The XRD result indicated the homo crystalline phase formation
in all blends and no stereocomplex crystal. The in vitro degradation study indicated that PEG content is proportional to… More >
