摘要
开发核磁共振法测定异戊二烯橡胶微观结构的新方法。该方法通过二维同核及异核相关谱对异戊二烯橡胶中顺式-1,4-结构、反式-1,4-结构、3,4-结构等进行定性分析,并仅用一维氢谱即可对异戊二烯橡胶中的3种微观结构进行定量分析,操作简便,变异系数小于0.001。
A new method for the determination of the microstructure of isoprene rubber by nuclear magnetic resonance(NMR)is developed.Through two dimensional homonuclear and heteronuclear correlation spectra,The qualitative analysis of iCIS-1,4-structure,trans-1,4-structure and3,4-structure of isoprene rubber are run by this new method.This method can be used for the quantitative analysis of3kinds of microstructures in isoprene rubber with only one dimensional hydrogen spectrum.The operation is simple and the coefficient of variation is less than0.001.
