Abstract

Blend materials of poly (D, L-lactide)/ poly (vinyl alcohol) (PDLLA/PVA), poly (D, L-lactide)/poly (ethylene glycol)300 (PDLLA/PEG300) and poly (D, L-lactide)/poly(ε-caprolactone) (PDLLA/PCL), obtained by solvent-casting, have been studied by differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FT-IR). DSC results showed that PDLLA/PVA and PDLLA/PEG300 are miscible in entire composition range and PDLLA/PCL blends are immiscible. FT-IR results indicated that there are hydrogen bond interactions in these blends except PDLLA/PCL. The miscibility of blends is enhanced; however, the plasticizing role is not affected by hydrogen bond interaction through hydroxyl end groups. With the increase of PEG300, the plasticizing role become obvious in PDLLA/PEG300. The effects of hydrogen bond interaction between poly (D, L-lactide) and other polymer chain were studied, the effects of the mixed temperature and solvent of the blends were also discussed.
