摘要：
The NMR spectra of poly(1,3-cyclohexadiene) (PCHD) were studied. PCHD was synthesized by living anionic polymerization of 1,3-cyclohexadiene (1,3-CHD) with the n-butyllithium (n-BuLi /N,N,N′, N′-tetramethylethylenediamine (TMEDA) system as an initiator. PCHD has a structure consisting of a main chain formed by 1,2-addition (1,2-unit) and 1,4-addition (1,4-unit). The complicated 1H and 13C NMR spectra of poly(1,3-cyclohexadiene) (PCHD) were observed. The spectral assignment of 1H NMR spectrum of PCHD with the 1,2-units and 1,4-units was determined by two dimensional (2D) and Distortionless Enhancement by Polarization Transfer (DEPT) NMR spectroscopy techniques.
