The miscibility of poly(D,L-lactide) (PDLLA) and poly(p-vinylphenol) (PVPh) blends has been studied by differential scanning calorimetry and Fourier transform infrared spectroscopy (FTIR). Phase separation was observed in blends over a wide composition range. A PDLLA-rich phase was found to coexist
## Abstract Blends of poly(Lβlactide) (PLA), containing from 5, 15, or 25 wt % potato starch, unmodified or hydrophobized in methane plasma, were prepared and studied. To enhance the drawability of the blends, the plasticization of PLA with 10 wt % poly (ethylene glycol) (PEG) was also employed. Th
