利用高分辨核磁共振谱仪研究了环氧乙烷－环氧丙烷均聚物和无规共聚物的核磁共振主链碳谱。在对其链结构进行有效归属的基础上，讨论了不同配比聚合物的核磁共振主链碳谱特点及其可能的单元链节排列顺序。
Nuclear magnetic resonance (NMR) backbone carbon spectra of ethylene oxide-propylene oxide homopolymers and random copolymers were studied using high-resolution nuclear magnetic resonance spectroscopy. Based on the effective assignment of its chain structure, the characteristics of the main chain carbon spectra of the different ratio polymers and the possible sequence of unit chain are discussed.
