摘要：

The inclusion complexes (ICs) of alpha- and gamma-cyclodextrins (CDs) with high-molecular-weight poly(butylene succinate) (PBS) were prepared and characterized by differential scanning calorimetry, Fourier-transform infrared spectroscopy (FT-IR), wide-angle X-ray diffraction, solid-state C-13 nuclear magnetic resonance (NMR) spectroscopy, and solution H-1 NMR spectroscopy. The resultant ICs were found to have channel structures. FT-IR data suggested that the ICs were stabilized by hydrogen bonds between the host CD molecules and the guest PBS chains. Through the formation of ICs, the PBS chain possibly adopts the kink conformation in the included state, as indicated by NMR analysis.
