Abstract
Biodegradable aliphatic polyester Bionolle (BN) and cellulose triacetate were cast-blended at 50°C by using chloroform solvent. Homogeneous blend films were obtained at various blend ratios. The structure of the blends was investigated using wide angle X-ray scattering method and differential scarming calorimetry. It was found that the weight percentage of BN in the blend (φ BN) affected the structure of the blends. BN molecules were not crystallized in the blends with φ BN_??_40%. On the other hand, BN molecules were crystallized in the blend with φ BN>40%. Transparent films were obtained in the case of CTA-rich blends. The tensile mechanical properties of the blends were markedly influenced by the difference of the structure of blends.
