Derivative polysaccharide, cellulose triacetate (CTAc) is blended to the combination of poly-hydroxybutyrate and its copolymer polyhydroxyvalerate (PHB-PHV) as the internal plasticiser. The blends films were analyzed by differential scanning calorimetry and X-ray diffraction. The DSC methode shows the miscibility of this blend by a single peak of glass transition temperature and a decrease in the melting point. By using a certain composition in mixing, the product shows lower crystalinity than plain PHB. The combination of such properties of these new blends will put PHB as a potentially new source of biopolymer material with a better processability window.
