摘要：

The compatibility of dextran (D) with maleic acid-vinyl acetate copolymer (MAc-VA) in the solid state as a thin film has been studied by coupling thermogravimetry and differential scanning calorimetry with infrared spectroscopy. Optical and electron microscopy have been also used to investigate the morphology of the blends. It has been established that blends with a content of dextran higher than 85 wt.% exhibit good compatibility, the morphology of the blends being a homogeneous fine particle dispersion, while blends with a prevalent MAc-VA copolymer content exhibit a tendency to phase separation.
