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.
