| 中文摘要 | to synthesize the copolyester of poly(beta-hydroxybutyrate) (phb) and poly(epsilon-caprolactone) (pcl), the transesterification of phb and pcl was carried out in the liquid phase with stannous octoate as the catalyzer. the effects of reaction conditions on the transesterification, including catalyzer concentration, reaction temperature, and reaction time, were investigated. the results showed that both rising reaction temperature and increasing reaction time were advantageous to the transesterification. the sequence distribution, thermal behavior, and thermal stability of the copolyesters were investigated by c-13 nmr, fourier transform infrared spectroscopy, differential scanning calorimetry, wide-angle x-ray diffraction, optical microscopy, and thermogravimetric analysis. the transesterification of phb and pcl was confirmed to produce the block copolymers. with an increasing pcl content in the copolyesters, the thermal behavior of the copolyesters changed evidently. however, the introduction of pcl segments into phb chains did not affect its crystalline structure. moreover, thermal stability of the copolyesters was little improved in air as compared with that of pure phb. |
