Abstract: A series of copolymers of β-Cyclodextrin and Epichlorohydrin were studied by means of 13C NMR, and spectral assignments were carried out. Their DEPT spectra checked the assignments correct. A group of α-substituted parameters of 13C NMR chemical shift at C(2)-O -, C(3)-O-and C(6)-O-positions of β-CD by 2,3-propanediol group was obtained. This paper investigated and described the compositions and the structural characterization of molecular chains in the copolymers.
