摘　　要：^(13)C NMR测定了一个系列的环氧氧丙烷与β-环糊精的共聚物,进行了谱峰归属和DEPT谱验证,实验测得2,3-丙二醇基在β-环糊精C(2)-O-位、C(3)-O-位和C(6)-O-位取代的^(13)C NMR化学位移α-取代效应参数,描述了该共聚物分子链的组成和链化学结构特征。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.
